Appearance method:Appearance identification mainly observes the appearance characteristics of plastic products through vision, touch, smell, etc., such as the shape, transparency, color, gloss, hardness, etc. of the product. After plastics are recycled and reprocessed, the color, gloss, strength, etc. will change. The color of plastics without recycled materials will generally be more transparent, and products […]

Three methods to detect internal stress of injection molded parts Plastic internal stress refers to an internal stress generated during the plastic melting process due to factors such as the orientation of macromolecular chains and cooling shrinkage.When the forces and entanglements between macromolecular chains cannot withstand this kinetic energy, the internal stress balance will be

The layout of the production workshop focuses on two aspects: to meet production needs, to optimize the layout according to the production process, and to meet the requirements for flexible energy use under specific production conditions. The injection molding machine is a major energy consumer in the injection molding workshop, and the energy consumption is

The first-level maintenance of injection molds refers to the daily maintenance of injection molds by operators during production. The main contents are cleaning, lubrication and inspection.

Industrial connectors are specifically designed to create a rugged Ethernet connection in harsh environments, making them tougher, stronger and more resistant than conventional connectors. Its application is not only limited to manufacturing but also used to withstand the test of the harshest industrial environments. For example, under vehicle conditions, adapting to strong vibration environments is

Compression injection molding: (injection compression molding) is an advanced form of traditional injection molding.Advantages: It can increase the flow length ratio of injection molded parts; use smaller clamping force and injection molding pressure; reduce material internal stress; and improve processing productivity.Injection compression molding is suitable for products made of various thermoplastic engineering plastics, such as

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

A two-color mold refers to a mold in which two plastic materials are injected on the same injection molding machine and molded in two times, but the product is only ejected once. Generally, this molding process is also called double-material injection molding, which is usually completed by a set of molds and requires a specialized
