Pipe Fitting Mould Commonly Used Steel

Mold steel

Several commonly used steel

Steel is the decisive factor in the quality of the mold, choose a reasonable steel is the most important. The criteria for selecting steel are:

① the requirements of injection molding materials - different plastics to use different steel, such as the requirements of high polishing, corrosion-resistant requirements and so on;

② the price of steel products to use with the better, Pipe Fitting Mould not the more expensive the better; taking into account the cost of mold factors, mold steel and die to choose the corresponding material, to avoid unnecessary waste; general P20 life of about 30 million; 500,000 no problem, H13 / 2344 usually 80-100 million or more, according to the situation to choose;

③ heat treatment. The surface treatment of the mold is also very important. Nitriding - can enhance the surface hardness of steel, effectively extending the die life; plating - can effectively modify the mold steel, for some need high brightness and corrosion-resistant plastic parts can use electroplating to enhance and improve the performance of steel

Pipe fittings design

Mature mold structure not only take into account the product material properties - shrinkage, molding temperature, elastic tensile deformation coefficient, but also take into account the cooling water, open the mold speed. Reasonable mold structure can effectively extend the life of the mold and ensure the smooth production of mold. Improve efficiency and reduce costs

To be good at work, we must first of its profits. Mold process arrangements are particularly important, reasonable process arrangements to speed up the production cycle, Pipe Fitting Mould shorten the processing time, effective cost savings. And more importantly, accurate and reasonable processing to ensure that the mold in the production process of stability and extended life. Processing errors will lead to mold welding, no matter how good the welding, the mold is a loss; another poor processing may also affect the mold action, reduce die life, Pipe Fitting Mould resulting in mold in the production process of cracking Even broken.

Determine the bucket capacity is the lowest piece of wood. This reason we all understand, but often do not pay attention to the time. Mold is the same, although the standard parts are not directly involved in molding, but it controls the operation of the entire mold. Good standard parts should be able to wear, hard enough, high precision, not deformation. Different brands of standard parts difference is very large, Pipe Fitting Mould so do not blindly bargain mold, kill to kill, your mold from the Mercedes-Benz straight down to the public.

On the touch is the experience of mold fitter, seemingly simple live but the most technical content of the work. Complex mold is mainly to see this effort. Flat mold the most simple, Pipe Fitting Mould as long as the fractal surface as long as there is no flash off the basic ok. Like auto parts mold is very troublesome, not only the fractal surface is relatively irregular, and often includes multiple sliders, top blocks. At the same time through the touch can also be on the mold of other issues to improve and improve. So it is a comprehensive work.

The polishing of the mold is the last part of the mold making. Polished directly reflected in the plastic parts, so this is the most face of the work. Polishing can also help and replenish the mold action, especially for the mold is very meaningful. Often some mold production is not smooth because the light is not in place,Pipe Fitting Mould the resistance is too large, stripping difficult, and even the top white, the top crack and so on.

Mold assembly is the same as the assembly machine, each component, each screw can not be wrong, otherwise the consequences will be very serious, ranging from product defects, Pipe Fitting Mould affecting production, while the damage to the mold, resulting in scrapped. So the assembly of the living must be very detailed. In particular, the assembly process should pay attention to the cleaning work of the mold, especially the waterway, screw holes, must blow clean inside the iron, otherwise the customer is very angry.
