Before the design of the Crate Mould(FURNITUREMOULD) https://www.furnituremould.com/
, the designer should fully analyze whether the plastic products conform to the principle of injection molding, and need to negotiate with the designers of the products, and a consensus has been reached. These include the geometry, dimensional accuracy and appearance requirements of the product, and the necessary discussion to avoid unnecessary cumbersome manufacturing of the crate mould.
Second, the crate mould structure design.
A set of high-quality crate mould requires not only good processing equipment and skilled crate mould, but another very important factor is the design of good crate mould , especially for complex crate mould. The quality of the mould and crate mould is more than 80% of the quality of the crate mould. An excellent crate mould design is: under the premise of meeting the requirements of customers, the processing cost is low, the processing difficulty is small, and the processing time is short.
To do this, we must not only fully digest the requirements of the guests, but also have an understanding of the injection molding machine, the mould structure, the processing technology and the processing capabilities of the mould factory itself. Therefore, to improve the design level of crate mould, the following points should be achieved:
1. Understand every detail in each crate mould design and understand the purpose of each part in the crate mould.
2. In the design, refer to the previous similar design, and learn about the situation in the processing and production of the crate mould, and learn from the experience and lessons.
3. Learn more about the working process of the injection molding machine to deepen the relationship between the crate mould and the injection molding machine.
4. The factory understands the process of processed products and recognizes the characteristics and limitations of each process.
5. Understand the test results and mould changes of the crate mould designed by yourself, and learn the lesson.
6. Try to use the previously successful crate mould structure when designing.
7. Learn more about the impact of the crate mould on the product.
8. Study some special crate mould structures and learn about the latest crate mould technology.
Third, determine the crate mould materials and selection of standard parts.
In the selection of the crate mould material, in addition to the accuracy and quality of the product, it is necessary to give the correct choice in combination with the actual ability of the mould factory for processing and heat treatment. In addition, in order to shorten the manufacturing cycle, the existing standard parts are utilized as much as possible.
Fourth, parts processing and ladle mould assembly.
In addition to the optimum structure and reasonable tolerances of the design of the crate mould, the machining of the parts and the assembly of the moulds are essential. Therefore, the selection of machining accuracy and processing methods is absolutely dominant in the manufacture of crate mould.
The dimensional error of a molded product is mainly composed of the following parts:
1. The manufacturing error of the mould is about 1/3.
2. The error caused by mould wear is approximately 1/6.
3. The error caused by uneven shrinkage of the molded part is about 1/3.
4. The error caused by the inconsistency between the predetermined contraction and the actual contraction is approximately 1/6.
The total error = (1) + (2) + (3) + (4).
Therefore, in order to reduce the manufacturing error of the crate mould, the machining accuracy should be improved first. With the use of CNC machine tools, this problem has been well controlled. In addition, in order to prevent the error caused by the wear and deformation of the mould, in the case of the crate mould with high processing precision and large product output, the key parts such as the cavity and the core should be quenched. In the medium and large crate mould, in order to save materials and facilitate processing and heat treatment, the crate mould should be designed with a mosaic structure.
In order to solve the error caused by the uneven shrinkage of the molded part and the inconsistency between the predetermined shrinkage and the actual shrinkage, one third of the tolerance of the product is generally selected in the manufacture of the crate mould, as the manufacturing tolerance of the mould, the purpose of which is to give the molding process in the future. There is a large room for adjustment to resolve the errors caused by the molding process.

The first inspection of the ECCA Wire(XINYU) http://www.xinyu-enameledwire.com/
should be very important. It is very important to find problems at the beginning, to deal with problems, to develop preventive measures, and to avoid batch failure. For example, a worker opens the extruder in the morning, and when the temperature of the heating reaches, he starts to consume. Then this is the first piece of inspection, to check whether the temperature of the extruder has reached the regular temperature, the gloss of the discharged material, the presence or absence of colloidal particles, the non-plasticized particles, etc. If so, clarify that the holding time is not enough, this When the machine is turned on, it will inevitably lead to quality problems. When you find a product that is not suitable, you should analyze it and develop preventive measures. Regarding the first piece inspection, it can be introduced into self-inspection, mutual inspection and special inspection. Then, regarding the above three tests, I think that the self-inspection is the probability that the operator inspection is more dangerous than the special inspection, and there are many production machines in the workshop. It is impossible to each. The special inspections are all in place. At this time, the self-inspection should play the role of its position, which is also the gateway to prevent the inflow of non-products into the next process. But often the opposite is true. The inspection relies on the special inspection personnel. This is also a bad concept. The quality is the participation of all the people involved. It is not the obligation of that person. It is the duty of everyone. The progress of quality is established in the norm. Understand the level and the sensitivity of the application, everyone can be a quality inspector, change the concept, the problem will be solved.
2. Circuit inspection
The patrol inspection is the full inspection of the quality inspection process by the quality inspector. It is thought that the inspection of important processes and data enhancement frequency can be carried out at a time. It is necessary to urge the operators to familiarize themselves with the ECCA wire production process rules and check the execution status. If the inspection is not timely, a batch failure will also be formed.
3. Completion inspection
Completion inspection is a test method for a semi-disposable ECCA wire, and it is verified whether the ECCA wire meets the request rule.

products in domestic and commercial water treatment equipment. Although the reverse osmosis membrane itself has certain anti-pollution properties, if the RO membrane is not effective for a long time during the whole production operation, Protection, coupled with long-term accumulation of pollutants in the water, membrane fouling will occur.
At this time, the transmittance of the film is reduced, the membrane flux is lowered, the life of the membrane is greatly reduced, and the production running cost is continuously increased. Therefore, in the whole process of the reverse osmosis membrane, the analysis is carried out according to factors such as the process of the membrane, the amount of permeation, the performance of the membrane, and the correct method is maintained and improved.
It is necessary to carry out regular cleaning and maintenance, but pay attention to the influence of operating pressure on membrane fouling during the cleaning process. In the primary stage of membrane operation, due to the large adsorption between membrane and solute, increasing the operating pressure at this time can make Many solute molecules penetrate into the past, which in turn reduces membrane fouling.
However, an increase in operating pressure causes an increase in the deposition rate of colloidal substances on the surface of the membrane, which further accelerates the rate of membrane fouling. Therefore, in the actual operation process, the determination of the operating pressure should be reasonably selected according to the actual situation, and in order to better control the membrane flux, the corresponding warning value should be set, and when the transmembrane pressure difference reaches a certain value, the membrane cleaning is performed.

? It is recommended that you choose from three aspects: technology, certification and brand.
At present, most water purifiers use physical water purification, and the specific filtration methods are also different. There are UV technology, RO membrane technology and ultrafiltration membrane technology, these technologies have different degrees of water filtration. For the RO membrane, the water purifier with the RO membrane is called the home RO system and consists of a pre-filter, an RO membrane and a post-filter. The RO system for the home is more suitable for water treatment, not only is it purer, but also effectively removes heavy metals from the water and releases cations that are beneficial to the human body.
Compared to uncertified water purifier spare parts, of course, getting certified will give us more peace of mind. Currently, there are NSF, WQA, IAPMO and other certification methods. If one or both of them are certified, we can choose to purchase. For uncertified water purifier spare parts, we must be careful to purchase them as these may cause installation problems.
When buying water purifier spare parts, we often choose a good brand. The popularity of the brand is also one of the directions we buy water purifier spare parts. When we buy new water purifier spare parts, we will be more assured.
The choice of water purifier spare parts can be considered technology, certification and brand. If you choose a reliable water purification device for your family, you will drink healthier, cleaner water.

adopts the solar energy principle made by the photovoltaic effect principle. During the daytime, the solar panel receives the solar radiation and converts it into electric energy output. The solar LED street light is stored in the battery through charge and discharge control, and the night illumination gradually decreases to about 10LX, and the solar panel voltage is gradually reduced. It is about 4.5v, the charge and discharge control device detects the voltage after the operation, the light source of the battery discharge, the battery discharge set time, the charge and discharge control operation, and the solar LED street light completes the battery discharge.
Solar panels reach 127Wp / m2 solar power, high power, the system is conducive to windproof planning; some lamps are integrated into the printed circuit board with 1W white LED and 1W yellow LED, arranged as a planar light source with a grid of certain spacing.
The control box body is made of stainless steel, which is beautiful and elegant. The control box is placed with maintenance-free lead-acid battery and charge and discharge control. The system uses a valve-regulated sealed lead-acid battery, because it has little maintenance, so it is also called "maintenance-free battery", which is conducive to the system maintenance cost reduction; the planned charge and discharge control coordination completion function (with light control, Time control, overcharge maintenance, over-maintenance and reverse maintenance, etc.) and capital manipulation to complete high prices.

may only have one stamp or multiple, sometimes as many as 100, depending on the size of the component. Furniture mould typically produces similar components, but one type of mould, commonly referred to as a "family" mould, is used to make the various components, which are then assembled into individual components.
The main structural component of the furniture mould is the mould baffle, which is locked together by the use of pins and bushings to maintain and align the inner working parts with the mould. In operation, one piece of furniture mould part is held in a secured state on the moulding machine. The other half is removed from the fixed portion to complete the mould closing and opening. The fastening portion from the mould contains a method for transporting the molten polyester resin into the passage therein.
The method consists of an inlet (runner) coupled to it (channel) to transport the polyester resin from the runner to the gate (inlet). The component ejection mechanism is usually fixed in the displacement portion from the mould. The furniture mould is designed using a cooling method to remove heat from the heat of fusion.
The polyester resin within the impression and thus the sale of components or components. Rapid cooling reduces machine injection time and enhances manufacturing while cooling and charging evenly.
Warpage or excessive shrinkage is prohibited by the component. Even component cooling requires that most of the condensing cooling occurs near the hottest point (ie, near the gate and inlet, and within the different sized components, in the largest sized position).

have become a global trend, providing brighter light and better visibility to residents around the world to reduce costs and carbon emissions.
Benefiting from the development of electrical technology, street lighting products have evolved from previous fuel-powered lamps to sodium-filled bulbs and LEDs. At present, new luminaires with smart sensor LED street lights can be automatically turned on or off according to changes in the surrounding environment.
A company from Norway has developed almost a new system that automatically dims according to the presence of traffic. Each lamp is equipped with sensors for detecting vehicles and pedestrians. With the support of LED street light manufacturers, these lamps can significantly reduce energy costs with new LEDs.
When a person or vehicle approaches, it emits a brighter glow to provide a brighter visual effect. If it does not detect any objects in motion, it dims the lamp at low power to reduce unnecessary power consumption.
When such a lamp supported by the LED street lights manufacturers are put into use, it is estimated that about 40% of the energy will be reduced compared to before applying.

guidelines in the UK and many other countries are currently based on suspicious evidence. That's why the Public Lighting Research Group at the University of Sheffield conducted a research project to understand the relationship between lighting and the sense of security after dark, and to improve the evidence on which the public lighting guidelines are based.
In a recent experiment, we asked people to walk on some streets in Sheffield at night and assess their sense of security. We also require these people to walk and rate the street on the same day to create baseline security measures and consider the deviations that may occur if the safety rating is taken only after dark.
The difference in safety levels between day and night walks tells us about the lighting on that street, the smaller the difference between day and dark levels, and people feel safer because of lighting. We compared the different ratings of the participants to the lighting metrics on each street, including the average illuminance (the amount of light falling on the street surface) and the uniformity (the degree to which the illumination is evenly distributed).

accounts for 40% of urban electricity use, while overall lighting is estimated to account for 1.5% of the country's electricity consumption. As one of the world's largest energy consumers, the potential for energy savings from Indian lighting improvements is evident. Increasing the energy efficiency of public lighting will also support other important priorities, including improving the safety and security of pedestrians and vehicles, promoting energy security, and easing local government financial pressures. But for now, these savings have not been developed.
This is the key message for the public lighting conference held in New Delhi from March 19th to 20th, 2014. Sponsored by ESMAP, the conference brought together representatives from more than 20 countries to discuss how India can best take advantage of this huge opportunity, as well as potential lessons from other countries.
The meeting focused on the main obstacles to developing energy-efficient public lighting in developing countries. Participants studied lessons learned from institutional and regulatory frameworks in developed markets, the role of energy service companies (ESCOs), and policy incentives to promote the development of energy efficiency projects.
Dr. Ajay Mathur, Director of the Energy Efficiency Bureau of India, talked about his vision to change all of India's 33 million street lamps into energy-saving LEDs. He believes that this streetlight technology is mature enough to provide better options. He said that although this transformation involves a variety of technical and financial risks, BEE and related organizations are looking for specific solutions, such as performance contracts, and models that make the industry sustainable.
Many participants agreed that if India turned to LED street lights, the benefits would outweigh the risks. Due to its long service life, turning LEDs can reduce the maintenance costs of municipalities by 20-25%.
