How to Correspond to TD Heat Treatment

A: Investigate the rolling direction of material, and treatment conditions of heat treatment
B: Visit factory of TD processing
C: Collect the technical requirements of TD processing
According to the above aspects to carried out the work, and collated information to reported to the customer.
We visited metal supplier last week , also is our long-term partners,
1. Due to the size of the product is very precise, 0.003-0.005 tolerance, 0.002 film thickness of TD treatment, but because of some errors, the size may be deviate after the TD treatment
2: TD treatment is high temperature treatment, and the temperature of treatment is 400~ 450, which is very strict for the heat treatment process of the product, and the material itself is very pure and stable.
3: Due to the deep and narrow grooves of the products, need to add something, so maybe there won’t be a plating
Based on the above points, we have difficulty in handling TD treatment, and we may not be able to produce satisfactory products by the customer. What should we do?
Finally, based on some of the above problems, We discussed the materials and heat treatment with Hitachi metals company. Hitachi engineer Mr. Gao has been repeatedly tested and recommended material for us (based on the customer’s confidentiality agreement, it is not convenient to specify the material ) and the process of heat treatment, which can guarantee the material of rolling direction, the stability of the grinding after heat treatment, and the stability of the TD processing; At the same time, technical director of Jac-Tec was used on some of the Toyota’s molds, :
1, The hardness of KS-G is 300 higher than TD’s HV2500 and harder
2. The KS-G coating is very uniform and the dimension is stable 0.0015
3: The temperature is lower than TD;
For these reasons, we agreed that we could give a proposal to the client.
After our detailed instructions, our customer finally agreed with our solution, TD and KS – G each do 10pcs to do the test. After testing, the customer found that the test of KS – G is better, blanking’s lifetime 2 million times! The customer is very satisfied that we can positively correspond, and also provide multiple choices, the customer also encouraged the follow-up to the technical improvement plan, to better serve the end customer!
