Customized Plastic Press-in Threaded Inserts FAQ
Q1：How to choose the right material for threaded inserts?
A: When choosing the material for threaded inserts, you need to consider the environment in which the plastic products are used, the load requirements, corrosion resistance and cost and other factors. Stainless steel is suitable for high temperature, high humidity and corrosive environments; brass is suitable for electrical connections and decorative requirements of high occasions; zinc alloy is suitable for the weight and cost requirements of the occasion.
Q2：How to determine the press-in depth of threaded inserts?
A: The press-in depth of threaded inserts should be considered according to the wall thickness of plastic products, thread specifications and assembly requirements. Usually, the press-in depth should ensure that the threaded inserts are closely combined with the plastic parts, and at the same time, avoid over-pressing resulting in the rupture of the plastic parts.
Q3: How to ensure the assembly quality of threaded inserts?
A: The key to ensure the assembly quality of threaded inserts lies in precise size control and good fit. In the manufacturing process, the dimensional accuracy of threaded inserts and plastic products should be strictly controlled to ensure a smooth and close fit during assembly. In addition, the use of specialized press-in equipment and processes can also improve assembly quality.
Q4：What are the fixing methods of threaded inserts in plastic products?
A: The fixing methods of threaded inserts in plastic products mainly include press-in type, heat fusion type and ultrasonic welding type. Among them, the press-in fixing method is the most commonly used, it is through the threaded inserts pressed into the reserved holes of the plastic products, using the elastic deformation of the plastic to realize the fixing. Thermal fusion and ultrasonic welding are suitable for occasions with high requirements on assembly strength and sealing.
Q5：How to check the quality of plastic press-in threaded inserts?
A: The quality inspection of plastic press-fit threaded inserts should check their appearance, size, thread quality and assembly performance. Appearance inspection includes checking whether the surface is flat, cracks or damage, etc.; size inspection includes measuring the diameter, length and thread specifications of the threaded insert; thread quality inspection includes checking whether the threads are clear, whether the fit is tight, etc.; assembly performance inspection includes checking the fit between the threaded insert and the plastic product, the firmness and sealing of the assembly.
