1) Viscosity curve The purpose of making a viscosity curve is to select a suitable injection speed injection molding process . When there are slight fluctuations in various parameters, it will not cause a large change in melt viscosity. The fluctuation between each mold should be as small as possible to ensure the repeatability of […]

Do you know how to design a plastic part embedded in a nut If: there is no problem in the selection of plastic and nut, the standard state of the nut after being embedded in the plastic is shown in Figure (I)If: the nut size is too small, the plastic BOSS hole is too large,

Two-color injection molding technology is also called double-material injection molding technology. This is a technology that uses two plastic materials to be mixed and injection molded to form plastic products. Its technical connotation is actually to use a mold component to shape the shape and mold it in the mold. Welding work, so the basic

The role of hot runner in plastic mold design Hot runner (HRS) is also called a hot water nozzle, which turns a solidified nozzle into a molten nozzle. Its composition is relatively simple and mainly includes a manifold, a hot nozzle, a temperature controller, etc. Among them, the manifold can be divided into I-shaped, The

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
