Six Injection Molding Processing Technologies For Plastic Products For Home Appliances
Original: | Author: Jasmine HL of DGMF | Publish Time: 2018-05-25 | 9946 Views | Share:
The molding and processing methods of plastic products for home appliances mainly include injection molding, extrusion molding, thermoforming, hollow molding, lamination molding, compression molding, transfer molding, foam plastic molding, casting molding, insert casting, sealing casting, etc., among which Mainly injection molding.

At present, some domestic enterprises can produce laser scanning molding machines and plastic powders, but the performance of the equipment is unstable, and the types of powders are also small.

3. Melt core injection technology

It is usually used to form special-shaped cavity products with high requirements on cavity roughness and accuracy, which cannot be processed by hollow forming or rotary forming methods.

At present, the application of this technology in foreign countries has been relatively mature, but it is still in an individual application state in China. The processing principle of this technology is that the core shape that forms the cavity is formed first, and then the core shape is used as an insert for injection molding.

Under the heating effect of the injection molded part, the core is melted and flowed out, thereby forming a cavity. The most important point to use this technology is to know the melting point of core materials and plastic parts. Generally, the core material can be selected from general-purpose plastics, thermoplastic elastomers or low-melting-point metals such as lead, tin, and the like according to specific conditions.
