1.What are the dimensions and specifications of mold date inserts? What types of mold date stamp can you produce?

We can produce Mold Date inserts in various specifications. Our product sizes can vary from D2.6 to D25. In addition to the standard length, we can also customize the length according to the specific requirements of customers.

2.What are the material characteristics of mold date stamp?

Our mold date stamp are generally made of stainless steel SUS420. They have the characteristics of high hardness and not easy to rust. At the same time, we also have some models made of beryllium copper for better heat dissipation. Some other products are suitable for die-casting molds. Such mold date stamp are made of SKD61 material, which has a higher hardness.

3.Why some of the mold date stamp cannot be rotated after installation?

This is mainly caused by the following reasons: first, the opening of the mold date stamp is too small, which leads to the tight fitting of the m mold date stamp during loading. Second, the installation method is not correct. For some mold date stamp with replaceable core, it is necessary to screw out the core first during installation, and then tap the shell gently with a copper hammer, and then slowly screw in the core of it. In this way, the core of the mold date stamp will not be destroyed. Third, the temperature of the mold is too high. The temperature of some molds exceeds 150 degrees Celsius, which will lead to the decline or failure of the internal spring. It is suggested that high temperature resistant mold date stamp should be adopted for such high temperature molds.

4.What are the factors affecting the price of mold date inserts?

The first is the style of mold Date Inserts, some of which are more complex in design and have replaceable interiors. Mold Date Inserts like this tend to cost more because they require more production procedures and more precise fitting.

The second is the size of the mold date stamp, The cheapest size of our company’s mold date inserts is D6-D12. Due to the small size of D2.6-D5 mold date stamp, the processing difficulty is particularly great. Similarly, when the size exceeds D16, the price will be relatively high due to the factor of raw materials.

Third, the precision of mold date inserts will also have a significant impact. Some mold date stamp are less precise and have a large diameter error. An oversized diameter will cause trouble for mold date stamp when they are installed, and will not easily rotate the core behind them. Too small a diameter will cause mold Date inserts to fail to fit tightly into the mold cavity, causing a risk of shedding during production. Of course, these mold date stamp may be cheaper. THREEUP date Inserts are very precise, to within 0.005mm, and can be used safely.

Fourth, some mold Date inserts are produced with cheap raw materials, which have not even undergone heat treatment. mold date stamp have a poor hardness, and the cheap materials are vulnerable to corrosion or rust. THREEIP’s mold date stamp are all made of SUS420 stainless steel, all heat treated, rustless, and of high hardness. We hope we can provide better quality products and save you more cost.
