Gas Assisted Injection Molding The gas-assisted injection molding system uses an inert gas (usually nitrogen) directly injected into the plasticized plastic in the cavity through the sectional pressure control system to expand the interior of the plastic part to create a hollow shape, but still keep the surface of the product intact. Gas-assisted injection molding…
Injection Molding: Process Analysis Of Six Recycled Plastics First,recycled low density polyethylene (LDPE) process LDPE, the scientific name of high-pressure polyethylene, generally refers to plastic packaging film. Such as: woven bag inner liner film, food packaging film, daily necessities packaging film, greenhouse film. Most of these films are natural, light blue, and black. It is…
Solutions For Shrinkage Of Plastic Parts The problem of shrinkage of plastic parts (surface shrinkage and internal shrinkage) is due to defects caused by insufficient filling of the melt when the thicker part is cooled. We often encounter situations where the pressure is increased, the water inlet is increased, the injection time is prolonged, and…
Mould Manufacturing Finishing Process – Surface Treatment And Assembly The surface of the part is left with tool marks and wear marks where stress is concentrated and is the source of crack growth. Therefore, after the machining is completed, the parts need to be surface-strengthened, polished by fitters, and the hidden troubles in processing are…
Fifteen Tips For The Maintenance Of Injection Mould Compared with other molds, the injection mold has a more complex and precise structure and requires higher requirements for operation and maintenance. Therefore, during the entire production process, the use of positive solutions and meticulous maintenance, maintenance will maintain the company’s normal production and improve the company’s…
Mould Manufacturing Finishing Process – Grinding Of Parts There are three main types of machine tools used in grinding: surface grinders, internal and external cylindrical grinders, and tool grinders. The grinding deformation and grinding cracks must be strictly controlled during finishing grinding. Even very small cracks will be revealed during subsequent processing. Therefore, the feed…
Mould Manufacturing Finishing Process – Electric Machining Control The modern mold factory can not be lack of electrical processing, electrical processing can be all kinds of special-shaped, high-hardness parts for processing, it is divided into two kinds of wire cutting and EDM. The walking wire cutting accuracy can reach ±0.003mm and the roughness Ra0.2μm. At…
Application Of Long Glass Fiber Reinforced Polypropylene Materials In Automotive Long glass fiber reinforced polypropylene materials can be applied to instrument panels, door modules, front end modules, tailgates, and other internal and semi-structural applications that require balanced dimensional stability, heat resistance, and weight optimization. For example, ENLITETM LGF 1851, which was launched in October 2016…
Advantages Of Automotive Plastic Parts The advantages of automotive complex plastic parts: 1. The plastic can be processed at one time. The processing time is short and the accuracy is guaranteed. 2. The elastic deformation characteristics of plastic products can absorb a large amount of collision energy and have a large buffer effect on strong…
Application Of Injection Molding Process In Automotive Plastic Parts First of all, when commonly used resin materials such as bumpers and dashboards are modified resins such as modified PP and modified ABS, the resin materials have different hygroscopicity and meet the water content requirements during molding (general requirements ≤ 0.2 %)) The resin material must…
