Plastic wheel bushings, as a key mechanical component, are widely used in a variety of rotating and sliding systems to reduce friction, improve operating efficiency and extend equipment life. Compared with traditional metal bushings, plastic wheel bushings have become the preferred solution for many industries due to their lightweight, wear-resistant, self-lubricating and corrosion-resistant characteristics.
1.Plastic wheel bushing production process
Material selection and preparation: According to customer needs and application scenarios, select the appropriate plastic materials, such as polytetrafluoroethylene (PTFE), nylon (PA), polyoxymethylene (POM) or polyether ether ketone (PEEK).
Mold design and manufacturing: design and manufacture precision injection molds based on the size, shape and accuracy requirements of the wheel bushings.
Injection molding: inject the molten plastic into the mold, through precise control of temperature and pressure, to ensure the quality of the wheel liner molding.
Post-processing: deburring, trimming and surface treatment of the injection molded wheel bushings to improve their appearance and performance.
Quality Inspection: Conduct comprehensive inspection on wheel bushings in terms of size, hardness, abrasion resistance, corrosion resistance, etc. to ensure that they meet the design requirements.
Packing and shipping: Pack the qualified wheel bushings and prepare them for shipping to customers.
2.Plastic wheel bushing customization
Demand communication: Communicate with customers in detail to understand their application scenarios, load requirements, size limitations and special needs.
Program design: According to the customer’s needs, design the wheel bushing size, shape and material selection program, and provide preliminary design drawings and samples.
Sample making and testing: Make samples according to the design scheme and conduct actual testing to verify its performance and durability.
Modification and Optimization: Based on the test results and customer feedback, modify and optimize the design scheme until it meets all the customer’s requirements.
Mass production: After confirming that the design scheme is correct, mass production will be carried out and the consistency and stability of product quality will be ensured.
