Despite the fact that millions of objects are produced each year using this method of production, blowing is a complicated manufacturing technique.It is possible for defects to manifest themselves in a variety of ways, and they can manifest themselves in multiple ways.These issues are addressed in this booklet primarily as they manifest themselves in lightweight, thin-walled parts such as bottles and containers, which are the primary audience for this publication.Numerous solutions that have been proposed, on the other hand, have the additional benefit of being applicable to objects that are naturally heavier and thicker in nature.Some of the issues that could arise during blow molding operations will be discussed in greater detail in the following sections. Blow molding operations are a type of plastic injection molding process.

People who are considering the purchase of an extrusion injection blow mold machine must make certain that they do so from an established and trustworthy vendor in order to avoid disappointment.As you are probably aware, the highest-quality extrusion injection blow mold manufacturer machines operate smoothly and consistently, resulting in the production of high-quality finished products every time.Despite this, there are occasions when a variety of issues arise that necessitate the need for immediate attention. These problems could be caused by the use of inferior materials, the presence of a damaged mold, or the failure to follow the process instructions to the letter.

If you have a problem with your extrusion injection blow mold machine, you can always get in touch with the manufacturer from whom you purchased it.If you haven't already, it is highly recommended that you start by reading this guide, which will assist you in resolving some of the more common issues.

It is warpage that causes the oval-shaped neck and rounded bottoms with rocking motions to be produced, and it is also the cause of the rocking motions. Typically, this occurs because the blown product is not allowed to cool evenly and adequately before it is removed from the mold. Increase the amount of water that flows through the system to improve the overall performance of the system.Check to see if the problem is caused by an excessively high stock temperature by gradually decreasing it in small increments and seeing if the situation improves.

Extruded Product with Defects in the Wall — Another issue that can arise during the manufacturing process is the presence of defects in the wall of the extruded product.To ensure that there is no moisture present in the melt before starting an extrusion injection blow mold manufacturer machine, it is critical to check for moisture before starting the machine.Make sure that the resin has been given enough time to warm up and that any moisture has been absorbed before feeding it into the extruder to avoid this issue.

During the operation of extrusion injection blow mold machines, cold spots can appear on the wall of a blown object, manifesting themselves as non-homogeneous areas on the surface of the blown object.The majority of the time, this is caused by a lack of backpressure being applied.Another possibility is the presence of non-uniformity in the temperature distribution of the melt during the process.

Thinning of the weld — The most common cause of this phenomenon is an excessively high stock temperature compared to the recommended temperature.To understand why the process fails, it's important to remember that as the molds close and the pinch-off is formed, the process is unable to force enough material into the weld line.As a result, the weld does not have enough strength to hold together.It is possible to gradually lower the stock temperature on an extrusion injection blow mold manufacturer machine in this situation as a result of the above.When trying to adjust the length of the pinch-off territory, keep in mind that if that doesn't work, you might have to try something else.

Operators of extrusion blow mold machines also have to deal with the issue of tearring, which occurs on a regular basis.Perhaps a number of different factors are at play, and this is the result of their combined efforts. Most importantly, the amount of land that has been pinch-off is far too large in comparison to its size.In order to make it shorter, you would have to make it shorter yourself.Another possibility is that a pinch-off has become worn with use over the course of several years.If you find yourself in this situation, you have two choices: either temporarily roll things back or completely rebuild them.

Pitted bottle surfaces are indicative of the fact that you are working with a parison that is not quite up to standard.However, a mold surface of poor quality could also be at the root of the problem in some cases.If this is the case, it is likely that you will need to refinish the cabinets.The goal is to achieve a matte finish on the skin in this situation.As a result of the parison's ability to be quickly vented, it can conform to the surface even while the mold is still hot, resulting in a better fit for the part.
