Mold failure Since the surface of the plastic part is a reproduction of the mold cavity surface, if there are surface defects such as scars, corrosion, micropores on the surface of the mold, it will be reflected on the surface of the plastic part to cause gloss poor. If there is oily, moisture on the […]

Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (referred to as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make

When designing each injection molding product, we must first determine its mold opening direction and parting line to ensure that the core pulling slider mechanism is minimized and the influence of the parting line on the appearance is eliminated. 1. After the mold opening direction is determined, the product’s reinforcement ribs, buckles, protrusions and other

The Dragon Boat Festival, one of China’s most significant traditional festivals, commemorates the life and death of Qu Yuan, a patriotic poet from ancient China. Legend has it that in 278 BC, after learning of his motherland’s fall, Qu Yuan drowned himself in the Miluo River. The local people, deeply grieved, raced out in their

Finite element analysis is just one of many tools in an engineer’s toolkit to help solve problems and find answers. Its applications cover almost every aspect of interest, including force, shock, earthquake, temperature, noise, vibration, friction, durability, stiffness, and weight. Finite element analysis programs typically import CAD geometry and create a mesh that divides the

Dents are caused by local internal shrinkage after the gate is sealed or due to insufficient injection. Depression or micro-depression on the surface of injection molded products is an old problem in the injection molding process. Dents are generally caused by the increase in the wall thickness of the plastic product, which causes a local

Due to the high light transmittance of transparent plastics, the surface quality of plastic products must be strictly required, and there must be no markings, pores, mould or whitening. The defects such as fog halo, black spots, discoloration, poor gloss, etc., thus the raw materials and equipment are used throughout the injection molding process.The design

Plastic varieties: During the molding process of thermoplastics, there are volume changes caused by crystallization, strong internal stress, large residual stress frozen in the plastic parts, strong molecular orientation and other factors. Therefore, compared with thermosetting plastics, their shrinkage rate is larger, the shrinkage rate range is wider, and the directionality is obvious. In addition,

Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material. The toughness of the mold mainly depends

Injection molding: also known as injection molding, its principle is to add granular or powdered raw materials into the hopper of the injection machine. The raw materials are heated and melted into a flowing state. Under the push of the screw or piston of the injection machine, they enter the mold cavity through the nozzle
