PVC (polyvinyl chloride) key chain is a common key chain production materials, with soft, durable, waterproof and other characteristics. The following is a general PVC key chain production process:
Design Preparation: Begin by preparing a design pattern. You can use computer-aided design (CAD) software or other graphic design tools to create your design. Ensure that the design meets your requirements and includes the desired details and colors.
Mold Making: Create a mold for the PVC key chain based on the design pattern. Typically, molds can be made using silicone or other suitable materials. Ensure that the mold's dimensions and shape match your design.
PVC Material Preparation: Prepare the PVC material, usually in the form of pellets or sheets. Select the appropriate PVC material to ensure its quality and durability.
Heating and Injection: Heat the PVC material to the appropriate temperature, making it soft and pliable. Then, inject the heated PVC material into the prepared mold. Ensure that the PVC material fills the mold adequately and forms the desired shape and details.
Cooling and Curing: After injection, place the mold in a cooling area to rapidly cool and cure the PVC material. This helps maintain the shape and stability of the key chain.
Cutting and Shaping: Once the PVC material is fully cured, remove it from the mold and perform necessary cutting and shaping.Depending on the design requirements, you may need to trim excess material or shape the edges.
Attachment Addition: As needed, add attachments to the PVC key chain, such as key rings, lanyards, or metal loops. Ensure that the attachments are secure and harmonize with the design of the key chain.
Inspection and Packaging: Conduct a quality check on the finished PVC key chains to ensure their appearance and functionality meet the requirements. Then, package them to protect the key chains and facilitate transportation and sales.
The above is the general PVC key chain production process. Please note that the specific manufacturing process may vary depending on the manufacturer and equipment. For large-scale manufacturing, specialized equipment and processes may be required to achieve efficient production.
