The main steel suppliers of TDL are LKM, Gröditz and ASSAB. We will choose USA and Japan steel for mold manufacturing according to mold requirements. Due to our reliable steel supplier, skilled technicians and high-end precision mold manufacturing equipment, our mold quality is guaranteed. 

TDL’s mold manufacturing capacity is 570 sets of molds a year, and the automotive industry accounts for about 40%, followed by related molds for medical equipment and consumer electronics products.

Our engineers design plastic mold according to plastic part features, the mold will be 2 PLATE MOLD, 3 PLATE MOLD, PIN-POINT GATE MOLD, HOT RUNNER MANIFOLD mold, THROUGHLY HARDEN mold (above 44HRC), PRE-HARDENED mold (below 44HRC).

The hot runner system we used for mold manufacturing are DME, MOLD-MASTER, SYNVENTIVE, HUSKY, INCOE, YOUDU, SM, and etc.

Plastic mold manufacturing process–EDM

EDM has high precision, can achieve machining accuracy of ±0.05mm to ±0.004mm; WEDM can reach ±2.5um machining accuracy, and roughness can also reach 0.15-0.2uRa; CNC surface finish can reach 0.29µRa, and small machine tools can reach 0.8µRa.

Different EDM have different performance, TDL updates the equipment every year to ensure higher quality mold manufacturing.

2. The minimum hardness of mold base material is 280BN. (DME #2 steel / 4140 steel)
3. The inner mold cavity/core steel must be as hard as 48~50HRC. All other details, such as sub-inserts, slides, heel blocks, gibs, wedge blocks, lifters, etc. should also be of hardened tool steels.
4. The ejection board must have guide posts.
5. Slides must have wear plates.
6. If possible, the mold cavity & core and slides should have temperature control.
7. For all cooling, it is recommended to use electroless nickel or 420 stainless steel plates. This can prevent rust and clean up garbage.

3. The inner mold cavity/core steel should be as hard as 48~52HRC at least, and the other useful mold components should also be treated in the same way.
4. It is recommended to use parting line locks for 102 class molds.
5. The following items may or may not be required. It depends on the final production quantity. It is recommended to check if the following items are used when make a plastic mold quotation.
A. Ejector plate guide post.
B. Slide ware plates.
C. Electroplating water line.
D. Electroplating mold cavity/core. 

SPI-SPE Class 103 Injection Mold

Cycles less than 500,000 shots, medium production mold

1. Detailed mold design required.
2. The minimum hardness of mold base material is 165BHN. (DME #1 steel / 1040 steel)
3. The inner mold cavity/core steel is P20 (28~32HRC) or high hardness (36~38HRC).
4. The rest of the requirements depend on the need. 

Class 104 Injection Mold

Cycles less than 100,000 shots, small production molds

1. The mold design is required.
2. The mold base material P20 (28~32HRC) can be made of mild steel or aluminum. (1040 steel)
3. The inner mold cavity/core can be made of aluminum, mild steel or other approved metals.
4. The rest of the requirements depend on the need. 

Class 105 Injection Mold
