PA(nylon)

Nylon (polyamide, abbr.as PA) refers to a injection molding plastic composed of polyamide resins, which can be obtained by polycondensation of diamines and dibasic acids, or by ring-opening polymerization of lactams formed by dehydration of amino acids. Different from PP, PE and PS, PA Nylon does not gradually soften with the rise of temperature, but […]

PMMA

Polymethyl methacrylate, abbreviated as PMMA, is an important injection molding thermoplastic that was developed in the earlier stage. The plastic features great transparency, chemical stability and weather resistance. It is easy to dye and process, with an aesthetic appearance, thus widely applied in the construction industry.         Chemical Formula: [C5O2H8]n Structural Formula: PMMA, an important

Slide

How the slide work in plastic injection mold? In a plastic injection mold, the mold opening action is leveraged to create a relative movement trend between the angle pin and the slide, so that the slide moves in two directions – the mold opening direction and the horizontal direction – to release it from the

Guiding system

What are the guiding and positioning mechanisms of an injection mold? Collectively speaking, the mold guiding mechanism is the component of an injection mold that aims to ensure the smooth movement and accurate reset of each moving part during mold opening and closing, so that they are not misaligned and deformed under the action of

Ejection system

Product ejection is the last step in the plastic injection molding process. After a product solidifies in the mold, an effective method is needed to eject it from the mold. Product ejection cannot be neglected, and during the ejection process, the product should be protected from deformation, ejector marks, cracking and other damages. So, this

Mold Cooling

During the plastic injection molding process, the mold temperature directly determines the plastic product quality and the molding efficiency. An excessively high mold temperature not only extends the cooling time and reduces production efficiency, but also causes the plastic melt to lose its original performance; an excessively low mold temperature affects the melt fluidity and

Hot runner

A hot runner system mold is equipped with heating devices on the sprue and runners, on basis of a traditional two-plate or three-plate mold, so that the plastic in the runner is always in a molten state, so as to eliminate or reduce cold slug for the runners. Pros of Hot Runner Systems 1.Reduce the
