Teflon injection molded fittings are products that are processed through the injection molding process using polytetrafluoroethylene (PTFE) material. PTFE is a polymerized polymer compound made of tetrafluoroethylene, which has a very low coefficient of friction, excellent heat and cold resistance, excellent chemical stability and excellent electrical insulation properties, which makes Teflon injection molded parts widely used in many industrial fields.
1.Teflon injection molding parts production process
Raw material processing:
Teflon raw materials need to be sieved, dried and other treatments to ensure its good fluidity, so that in the injection molding process can be uniformly filled with molds.
Mold design:
According to the drawings or requirements provided by customers, design the corresponding molds to ensure the dimensional accuracy and surface quality of the products.
Injection Molding:
Add the treated Teflon powder into the injection molding machine, after heating and pressure to make it molded in the mold. Temperature, pressure and time should be strictly controlled to ensure the quality of molded products.
Cooling treatment:
After molding, the Teflon products need to be cooled down, removed from the mold and cooled naturally, so that they can be cured for subsequent processing and use.
Inspection and trimming:
Finished products need to undergo strict testing and trimming to ensure that their dimensional accuracy and surface quality meet the requirements, to avoid cracks, bubbles and other defects.
2.Teflon injection molding parts customization
Demand communication:
In-depth communication with customers to understand their use scenarios, performance requirements and special needs.
Program design:
According to the customer’s needs, provide a variety of design options, including size, shape, color, etc., and assess the feasibility and cost of the program.
Sample making:
According to the solutions confirmed by customers, make samples for customers to confirm.
Batch production:
After the customer confirms the samples, mass production according to the order demand, and make sure the product quality meets the customer’s requirements.
After-sales service:
Provide product use guidance, technical support and after-sales maintenance services.
