What are the characteristics of extruded and injected blown hollow plastic products?
The advantages of extrusion blown plastic forming hollow products are: less investment in production equipment, simple equipment structure, easy mould manufacturing, high molding rate of hollow plastic products, uniform temperature control, and various specifications of hollow plastic products can be formed.The defect is that the wall thickness of the product is less uniform, and there is a seam line.
The advantages of injection blown plastic forming hollow products are as follows: the quality of the hollow plastic products is good, the shape size is accurate, there is no joint, the wall thickness is even, the multi-mode forming production is high, the automation degree is high, it is very suitable for the mass and high efficiency production of small container.The disadvantage is that the equipment and mold investment is large, the operation of production needs skilled operators
