Injection Molding Knowledge Center

Liquid silicone products have high transparency and no odor. The products have glue injection edges, no obvious mould pattern and hair edge defects. The appearance is more exquisite. Solid silicone products have low transparency, the smell of curing agents or other curing agents, the products are not injected with glue, the mould is closed at […]

There are numerous ways to classify automotive plastic molds according to the different plastic corridor molding, and processing styles can be divided into the following orders.    -Injection mold The molding process is characterized by placing the plastic material in the heated barrel of the injection machine. The plastic is heated and molten, pushed by

What is undercut? I believe that those engaged in the injection molding industry know, so I will not repeat it. The undercut is not a complex problem in injection molding, but it is common in almost all injection molding factories. The reason for this is that there are too many types of burrs, and the

I believe that the injection molding industry, injection molding technician positions above, have encountered the production process of injection molding products, due to water reasons, the production of products due to deformation caused by the lousy batch situation: deformation, visual inspection is challenging to find, only when assembled with, only to find that the assembly

The injection moulding process mainly consists of 6 stages: mold closing – filling – holding pressure – cooling – mold opening –Demolding, and other 6 stages. These 6 stages directly determine the moulding quality of the product, and these six stages are a complete nonstop process. also we concentrate on the 4 stages filling, holding

Thermosetting plastics are phenolic, amino (melamine, urea-formaldehyde), polyester, polypropylene phthalate, etc. Mainly used for compression moulding, extrusion, and injection moulding. Silicone, epoxy resin and other plastics are used mainly as low-pressure extrusion packaging electronic components and casting moulding.   1. Process characteristics   (A) Shrinkage rate   The size shrinkage occurs after the plastic part

Thermoset injection molding uses a screw or a plunger to pass the polymer through a heated barrel (120-260°F) to reduce density and fit it into the heated earth (300-450 °F). Once the material fills the world, it’s held under pressure.  At this point, chemical cross-linking occurs, causing the polymer to harden. The complex (i.e., cured)

There are so many different plastic injection molding machines out in the market today. This article is going to go over some of the main points to look for when deciding which machine to purchase and give you a thorough explanation of 5 things you should know about plastics vertical injection molding machine.   What
