Our Advantage

Fully automatic production

To ensure precision and consistency with every flat mold we produce, our manufacturing process is fully automated. This not only increases production efficiency but also minimizes error margins, resulting in flat molds that meet the highest quality and performance standards.

Excellent heat treatment

The hardness of the mold after heat treatment is a key factor in its performance and life. Nisun molds are heat treated to a hardness of 64-65HRC, ensuring optimal strength and wear resistance. Our commitment to superior heat treatment processes ensures that our flat dies are truly durable and able to withstand the most demanding threading applications.

Instruction & Maintenance

The regular maintenance of mold parts has a great influence on the life of the mold.

The question is: How do we maintain when using these components?

Step 1.Make sure there is a vacuum machine that automatically removes the waste at regular intervals. If the waste is removed well, the breakage rate of the punch will be lower.

Step 2.Make sure the density of the oil is correct,not too sticky or diluted.

Step 3. If there is a wear problem on the die and die edge, stop using it and polish it in time, otherwise it will wear out and quickly expand the die edge and reduce the life of the die and parts.

Step 4. To ensure the life of the mold, the spring should also be replaced regularly to prevent the spring from being damaged and affecting the use of the mold.
