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 […]

Updated November 3, 2026. Choosing an automotive plastic mold requires a documented match between the part, material, production machine and acceptance criteria. This checklist supports a supplier review; it does not replace a mold design calculation or a part validation program. 1. Freeze the Inputs for the Quotation Identify the part drawing and revision, material

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

Updated November 3, 2026. A thermosetting molding compound changes chemically as it cures. Its processing behavior is therefore described by more than a melting temperature. Resin chemistry, fillers, storage condition, temperature and time together affect the usable molding window. Flow and Cure Must Be Considered Together Heating can initially make a compound easier to process,

Updated November 3, 2026. Automotive plastic tooling can be described by the material process and by the way the mold handles inserts or multiple components. These descriptions overlap: an insert mold, for example, may also be a thermoplastic injection mold. Start with the part and material requirements rather than treating every mold label as a

Updated November 3, 2026. Thermoset injection molding depends on controlling material flow before the compound cures. A suitable process prepares the compound, fills the cavity and completes the required chemical crosslinking. The cured part is not made solid merely by cooling a reusable melt. Feed Preparation and Plasticizing Granular thermosets and dough-like BMC do not

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
