is mainly reflected in the machining precision of mould parts and the matching precision of relevant mould parts, which is a comprehensive index. High-quality parts for dustbin mould are the premise to ensure the mould precision, but no good mould assembly can also produce high-precision mould. Although restricted by the technical means of mould processing, the precision of general moulds should be coordinated with the precision of products.
The accuracy measured by the dustbin mould in the non-working state is the static accuracy of the mould. In the working state, the static precision changes due to the influence of the processing environment, which is called the dynamic precision of the die. The dynamic precision of the mould has real practical significance in actual production.
The main factors affecting the accuracy of the dustbin mould are as follows:
(1) Precision of product parts. The precision of the working part of the dustbin mould is higher than that of the product parts. The higher the precision of the product parts, the higher the precision of the working parts of the dustbin mould. The precision of the mould not only has a direct influence on the precision of the products, but also has a great influence on the production cycle and production cost of the mould.
(2) The level of technical means for the processing of dustbin mould. The level of processing precision, automation and other technical means of mould processing equipment is the basic condition to ensure the accuracy of the mould. The accuracy of the dustbin mould depends to a great extent on the technical means of mould processing.
(3) Technical level of dustbin mould assembly fitter. The guarantee of the precision of the mould needs high-level mould assembly fitters to realize, especially the roughness value of the polished surface of the mould mainly depends on the mould fitters to complete the mould. Therefore, the technical level of mould fitters is an important factor affecting the precision of injection mould.
(4) Production mode and management level of garbage dustbin mould manufacturing. The difference between production mode and management mode will affect the precision of the mould. For example, when designing and producing the die, whether to adopt "real matching method" or "separate manufacturing method" is an important factor affecting the assembly precision of the die.

The lower the temperature of the Air Cooler Mould(FURNITUREMOULD) https://www.furnituremould.com/
, the faster the heat dissipation due to heat conduction, the lower the temperature of the melt and the worse the fluidity. This is especially true when the injection rate is low.
2. Injection time
The impact of injection time on the injection moulding process is manifested in three areas:
(1) In order to shorten the injection time, the shear strain rate in the melt also increases, and the injection pressure required to fill the cavity needs to be increased.
(2) The injection time is shortened, and the shear strain rate of the melt is increased. Due to the shear thinning property of the plastic melt, the melt viscosity needs to be reduced in order to fully inject the injection pressure into the cavity.
3. Plastic materials
The complexity of the injection moulding process depends on the complexity of the plastic material. However, due to different materials, different brands, different manufacturers and even mass production, the performance of plastic materials varies greatly. Different material parameters can result in completely different product forming results.
4. Injection temperature
The melt flows into the cooled injection mould cavity, resulting in heat loss due to heat transfer. At the same time, heat is generated due to shearing, and this portion of heat may be greater or less than heat transfer loss, which is mainly determined by the injection moulding conditions of the automobile parts. The viscosity of the melt decreases with increasing temperature. Thus, the higher the injection temperature, the lower the viscosity of the melt and the less the required filling pressure. At the same time, the injection temperature is also limited by the thermal degradation temperature and the decomposition temperature.

has developed very rapidly in recent years, especially the wisdom of the country to promote urban lighting life. People advocate a vibrant and hopeful city life, so LED public lighting has also entered people's attention because the price of LED public lighting is not Unification leads to uneven product prices.
The following factors affect the LED public lighting price: 1, cost: the cost of LED public lighting manufacturers will be the main factor affecting the price. The cost is a variety of components of LED public lighting, generally including LED light source, electrical components, light controllers, signal poles and accessory lines. The cost per A component determines the final price. 2, scientific and technological progress: With the continuous advancement of science and technology, the price of controllers for pure electronic components will definitely decrease, thus lowering the street price of led. Of course, other parts will be accompanied by breakthroughs in new technologies to lower prices. 3, the trial product material is different: different manufacturers try different product materials, the surface looks exactly the same, because the cost of raw materials is different, resulting in price differences are also very common. Here, it is recommended that the purchasing department grasp the quality of the purchased products, and implement any procurement details. Do not give some irregular manufacturers shoddy, authentic, and have the opportunity to obtain qualifications.
For functional lighting, flexibility will result in interchangeability of the product, which needs to be constrained in the form of a specification or standard. However, the professional field does not require standardization, and the flexibility and plasticity of the LED can be fully utilized. For small and medium-sized LED public lighting manufacturers, this development is still a good opportunity to plan the market, adjust the price for LED public lighting, and With the continuous development of popular slogans, prices are no longer the only consideration for consumers. Under this view, the development prospects of LED public lighting will become better and better.

manufacturing process typically involves multiple processes such as forging, cutting and heat treatment. In order to ensure the quality of the furniture mould and reduce the production cost, the material should have good forgeability, workability, hardenability, hardenability and grindability. It should also have small oxidation, decarburization sensitivity, quenching, and tendency to crack.
1. Forgeability
It has low hot forging deformation resistance, good plasticity, wide forging temperature range, low forging cracking tendency, and reticulated carbide precipitation.
2. Annealing processability
The spheroidizing annealing temperature range is wide, the annealing hardness is low, the fluctuation range is small, and the spheroidization rate is high.
3. Cutting processability
Large cutting capacity, low tool loss and low surface roughness.
4. Oxidation, decarburization sensitivity
When heated at high temperature, the oxidation resistance is good, the decarburization rate is slow, and it is not sensitive to the heating medium, and the tendency to pitting is small.
5. Hardenability
Uniform after quenching, high surface hardness.
6. Hardenability
After quenching, a deep hardened layer can be obtained which can be hardened with a mild quenching medium.
7. Quenching deformation cracking tendency
The conventional quenching volume has small volume change, shape warping, slight deformation, and low abnormal deformation tendency. Conventional quench cracks have low sensitivity and are not sensitive to quenching temperatures and workpiece shape.
8. Grindability
The relative loss of the grinding wheel is small, the maximum grinding amount without wear is large, and it is not sensitive to the quality and cooling condition of the grinding wheel, and it is not easy to wear and grind the crack.

and injection moulding industry, you should not ignore the Chinese market. With the rapid development of the economy, it has become the center of the world's plastic mould manufacturers and injection moulding plants. But if you decide to outsource some table mould making or injection moulding business in China, how to find a list of table mould manufacturers will be your first challenge.
Finding a table mould maker in China is an absolutely tough job. It uses the survey process to make it the most consistent with the business model. This method assumes that all requirements and goals have been understood. There is no clear requirement that these jobs may be futile.
For potential suppliers, the best resources are Internet and industry publications. And the corresponding information should be compared and sorted according to logic. A screening list should be prepared prior to the investigation.
This process should avoid ambiguity and should be specific and clear. The goal is to find out if the supplier is compliant with the RFP requirements. The final table mould manufacturer should be able to meet these requirements. Then you can decide the final choice among them.
