The concept of a rotary blow mould involves using a pump to pressurise a mixture of molten steel and other fluids, to form parts. This then causes a block to be formed with cavities in it and these blocks are cooled off until the formation of the block is complete. After this the block is cooled dow... read more
Phenomenon 1: PET preform is opaqueReason: It may be because the raw material is dry and insufficiently plasticized; or mixed with other plastics, the purity is not high; and the temperature of the material is too low, which causes the PET preform to be opaque.Solution: Check whether the temperature... read more
Injection molding is a manufacturing procedure for making plastic parts either by manually injecting melted material into a mold, or by using a suitable machine. Injection molding can be carried out with a variety of different materials mostly consisting of plastics, polystyrene, acrylics, thermopla... read more
Plastic moulds are used for manufacturing plastic products. These include caps, plates, labels, eyewear frames, cushions and so on. In order to manufacture the products in desired shapes and sizes, plastic moulds are used. It saves time and effort when the mould is prepared properly. Here are some t... read more
Plastic molds have evolved from simple surface processing to all-round processing of surface and structural surfaces, from low-to-medium-speed processing to high-speed processing, and the development of processing automation control is very rapid. The clamping force must be sufficient.At present, ma... read more
