Detailed Process of Plastic Product Manufacturing
1. Raw Material Preparation and Pre-treatment
Yongli Plastic strictly controls the quality of raw materials, selecting suitable plastic pellets such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). These materials are screened, cleaned, and dried to ensure their quality and processability.
2. Heating and Mixing
The plastic pellets are melted in heating equipment to reach a processable state. During this stage, pigments or other additives may be introduced to meet specific product requirements.
3. Molding Processes
Yongli Plastic employs various molding techniques, including injection molding, blow molding, and extrusion.
Injection Molding: Molten plastic is injected into molds to form complex-shaped products, such as decorative boxes and plastic containers.
Blow Molding: This technique is used for hollow products like plastic bottles and storage containers.
Extrusion: It is employed to produce long, continuous products like pipes and films.
4. Cooling and Solidification
After molding, the plastic products are cooled and solidified to ensure their shape and performance stability. The control of cooling speed and methods is crucial for product quality.
5. Quality Inspection and Trimming
Each product undergoes strict quality inspection at Yongli Plastic, including visual inspection, dimensional measurement, and physical performance testing. Non-conforming products are reworked or remanufactured to ensure that only the highest quality products are released.
6. Packaging and Storage
Once inspected and approved, the products are packaged and stored, ready for shipment to clients worldwide. Yongli Plastic's market coverage extends to over 60 countries, including Europe, the USA, Australia, and Asia.
