Design of Thread Mould in Plastic Mould Factory
The threads of injection parts are divided into internal threads and external threads. The threads of threaded products are generally divided into standard threads, rectangular threads, trapezoidal threads, serrated threads and circular arcs.
Thread and V-thread. Exhibition. You can choose different shapes for different purposes, and you can choose serrated threads to meet your strength requirements. About today's commonly used
Bottles and capped screws are often tightened 1-2 times with bow screws in multiple directions.
Compared with metal, the strength of plastic is not high. Plastics are generally softer and the threads of plastic parts should be larger. If the diameter of the screw is small, it is better not to use the fine screw.
Otherwise, the shortening of plastic screw will be difficult to achieve the required strength. You can generally choose from the following table.
There are several methods of threaded injection moulding products.
1. Forming directly.
2. Processing method is adopted after processing.
3. Using metal threaded inserts, this method is often used in situations requiring re-assembly and disassembly as well as greater mechanical strength.
