Sino is a professional and world famous plastic medical high precision mold manufacturer. In recent years, in the field of high-precision mold, such as medical treatment, sino also has been a major breakthrough in the industry respected, the object of worship.

 In the medical field of high precision molds, Sino has its own professional produced ideas. Such as medical needle mould, injection mould is a precision, products need to contact with body, so the product inspection requirements are very strict, if you don't have rich experience in it , its difficult for people to do a good job really, there is a great probability to be scrapped.

 First of all, the selection of mold steel, mold is suggested to choose a high hardness, HRC35 degrees above the steel material is the most appropriate, generally you can choose nak80/S136 steel. The heat distortion of the mould is small, and the discharge is good. Secondly, the control precision is very important, because the puncture needle products is very small, the smallest hole size is only 1mm in diameter, but also have to ensure the concentricity of the core, this is a test of mold processing and processing of the precision of equipment. We choose the processing equipment used in the import of high-speed lathe. As far as possible to choose the equipment for less than 5 years, because the number of equipment years has been the actual machining accuracy has deviated from the direct impact on the formation of products. The needle to use copper electrode is not easy to wear, high-speed carved in place after the die and then hit the mirror EDM in place (it should be noted here that spark gap control).

 Third: the glue outlet choice, this product will generally choose the design structure of multi cavity mold, hot runner to latent imported glue, glue for export on slope, it is prone to pull the gum of the mouth, this time latent EDM adhesive is particularly important, as far as possible in the spark gap is less than 0.01.

 Finally, with the needle cap assembly, needle cap relative to the needle is still relatively simple, not too high detection standards, as long as the needle can be matched with the.
