When the injection molding factory tested the mold before production, all the mechanisms were running basically normally, but the product had serious appearance quality problems, with radial white marks on the surface. And these white marks became more serious as the glass fiber content increased, This phenomenon is commonly known as “floating fiber”, which is […]

What issues need to be paid attention to when producing PC polycarbonate products? PC has excellent performance, high transparency, good impact toughness, creep resistance, and wide operating temperature range. Process characteristics of PC: The melt viscosity is less sensitive to shear rate, but more sensitive to temperature, has no obvious melting point, the melt viscosity

Single parting surface injection mold When the mold is opened, the movable mold and the fixed mold are separated to take out the plastic parts. This is called a single parting surface mould, also called a double-plate mold. It is the simplest and most basic form of injection mould. It can be designed as a
What Are The Classifications Of Injection Mold Read More »
Cavity layout. The number of cavities and their arrangement are determined based on the geometric structure characteristics of the plastic part, dimensional accuracy requirements, batch size, difficulty in mold manufacturing, mold cost, etc. 2. Determine the parting surface. The position of the parting surface should be conducive to mold processing, exhaust, demoulding and molding operations,

Integrated hinge Product logos are generally placed on the flat inner surface of the product in a raised form. Choosing a surface where the normal direction may be consistent with the mold opening direction can avoid strain. Due to the unevenness and uncertainty of shrinkage during injection molding, the accuracy of injection molded parts is
