The use of recycled plastic materials in injection molding manufacturing has become very common. Common recycled plastic materials include polyethylene, polypropylene, polystyrene, etc. Using recycled plastic injection molding can not only bring good economic benefits, but also meet environmental protection needs.
Recycling sources
1. Injection molding waste: waste in the plastic manufacturing process, such as scraps and unqualified plastic products.
2. Consumer waste: discarded plastic products after use from households or businesses.
Processing before injection molding
Cleaning and separation: Recycled plastic materials must be thoroughly cleaned before injection molding to remove impurities and contaminants, and classified according to materials.
Crushing and processing: Clean plastic materials need to be crushed into small particles and then processed into pellets.
Injection molding use
During injection molding, new plastic materials and recycled plastic materials are mixed in proportion and dried. In order to improve material properties, various additives, such as reinforcing agents, stabilizers, etc., are also added to improve the quality of injection molded products. The following points need to be noted:
1. The quality of recycled plastic is not as stable as new materials, and there may be impurities and degradation problems.
2. Recycled plastic may have problems such as poor fluidity and uneven color during the injection molding process.
3. Some products have high requirements for material quality, and recycled plastics may be difficult to meet these requirements.
Plastics that can be made
Such as bottles, containers, lids, trash cans, storage bins, hangers, bumpers, pipes, floor tiles, insulation boards, etc.
Can injection molding machines use recycled plastic?
Injection molding machines can use recycled plastic to produce plastic products. Not only can it improve the utilization rate of recycled plastics, but it can also reduce environmental pollution and is in line with the concept of sustainable development.
However, the recycled plastic requires complex processing before injection molding. And before use, it must be suitable for the products being manufactured to meet the market demand for plastic products.
