As an important part of modern connectors, plastic threaded rods and nuts are widely used in many fields such as automotive, electronics, machinery, furniture and so on due to their lightweight, corrosion-resistant, good insulating and easy processing and molding characteristics. They not only simplify the assembly process, but also provide good fastening effect, and are indispensable elements in industrial production and daily life.
1.Plastic threaded rod and nut production process
Mold design and manufacturing: design and manufacture high-precision injection molds according to customer needs and product design requirements to ensure the accuracy and fit of the threads.
Raw material selection and pretreatment: Select plastic raw materials that meet the requirements, such as nylon (PA), polypropylene (PP), polycarbonate (PC) or polyoxymethylene (POM), etc., and carry out drying, mixing and other pre-treatment, in order to improve the fluidity of the material and the quality of the finished product.
Injection molding: The pre-treated plastic raw material is heated to a molten state and injected into the mold. Through the pressure and temperature control of the injection molding machine, the plastic is cooled and solidified in the mold to form the initial shape of the threaded rod and nut.
Threading: For rods and nuts that require precise threading, mechanical or laser processing techniques are used to thread the rods and nuts to ensure the accuracy and fit of the threads.
Post-processing and inspection: The injection-molded threaded rods and nuts are trimmed, deburred, cleaned, etc., and inspected in terms of size, appearance, performance, etc., to ensure that they meet the requirements of customers and industry standards.
2.Plastic threaded rod and nut customization
Demand communication: Communicate with customers to understand their application scenarios, installation requirements, material preferences, thread specifications and other detailed information.
Design customization: According to the customer’s needs, design the size, shape and thread specifications of the threaded rods and nuts, and provide 3D models for the customer’s confirmation. At the same time, the processability of the material and the performance of the finished product are considered to ensure the rationality of the design.
Material selection: According to the application environment and performance requirements, we recommend suitable plastic materials for customers and explain their advantages and disadvantages. Customers can choose materials according to their own needs.
Sample production and testing: According to the design scheme, we produce samples and conduct performance tests, including tensile strength, hardness, temperature range, etc., to ensure that they meet the customer’s needs.
Mass production and delivery: After customers confirm the samples, mass production will be carried out and delivered to customers according to the agreed time and method. At the same time, provide necessary technical support and after-sales service.
