Pipe Fitting Mould Increasingly widespread
- Jul 06, 2017 -

For PE pipe fittings, it is now increasingly widely used in our lives. Which accounted for about 80 injection molding technology. Injection Molding PE pipe fittings are widely used in automobile, construction, household appliances, food, medicine and so on because of its forming, precise size, with inserts, high productivity, easy to realize modernization and low processing capacity. The choice of plastic mold, for the plastic industry can receive good economic benefits is very critical, therefore, mold designers understand the basic requirements of mold materials and select the appropriate material is necessary.

PE pipe mold working conditions and cold stamping die is generally required to work at 150 ℃ -200 ℃, in addition to a certain pressure, Pipe Fitting Mould but also to withstand the temperature. Is based on the use of plastic molding mold conditions, different processing methods will be the basic performance of plastic mold with steel generally summarized as follows:

PE pipe die hardness is usually below 50-60HRC, Pipe Fitting Mould the heat treatment of the mold should have sufficient surface hardness to ensure that the mold has sufficient stiffness. Mold in the work due to the filling and flow of plastic to withstand greater compressive stress and friction, the mold to maintain the shape of the accuracy and dimensional accuracy of the stability, to ensure that the mold has sufficient service life. Mold wear resistance depends on the chemical composition of steel and heat treatment hardness, Pipe Fitting Mould so improve the hardness of the mold is conducive to improving its wearresistance

Excellent cutting: Most PE pipe mold, in addition to EMD processing need to be a certain cutting and fitter repair. To extend the service life of cutting tools, improve cutting performance, reduce surface roughness, pipe mold steel hardness must be appropriate.

Pipe mold processing generally need to go through the processing procedures are CNC milling, EDM, line cutting, carving, drilling, grinding machines, etc., Pipe Fitting Mould according to the requirements of the mold processing process are not the same, some customers have special requirements on the surface of the product We have to consider which process will meet the requirements of the customer, but basically the domestic mold are almost, in addition to the national standard is the standard, GB mold are fixed specifications in accordance with national standards to do, and the enterprise standard is not the same, Pipe Fitting Mould This is entirely based on the needs of customers to develop, and some customers in order to save costs to consider these! Many types of pipe fittings, such as the material to have a different category, each category can be subdivided a lot of specifications.

The mold forming process, the pipe mold structure and the production process are analyzed. To ensure that the die mold life of up to 50 million times; must design a complete mold structure and processing parts, and put forward the assembly requirements and injection molding process requirements; resulting in plastic parts appearance quality defects (such as shrinkage, etc.) or mold structure problems (such as sub- , Gate settings,Pipe Fitting Mould mold life can not guarantee such problems).

1, pipe mold appearance: pipe mold mold appearance must ensure that no rust, no collision marks, no residual defects and other modules defects;

2, pipe mold transport: mold transport must be installed on the mold, packaging, solid, rust;

3, pipe mold material: in the mold delivery at the same time, must provide a set of mold parts and maintenance of reference materials.
