Characters of Mold for Heat Sink Products
1. Mold manufacturing: The main characteristic of heat sink part is that it has many ribs, and electrode discharging and polishing are the main manufacturing processes on the mold, whose costs are both relatively high.
2. Part forming: For ribs (especially for deep and thin ribs), venting is difficult and it tends to trap easily. In the meanwhile, the ribs are hard to form, and the venting system is hard to design on the mold. This is why vacuum system should be applied to this type of products sometimes.
3. Common problems of mold during production: Die Sticking, Die Cracking:
A. Die sticking: For this kind of mold, die sticking happens easily because the strength of ribs is usually weak, and the temperature is very high on the mold's rib feature during mass production. To this issue, we usually suggest to apply nitridation on the mold cavity surface to improve surface hardness and smoothness, so as to decrease the rate of die sticking.
B. Die cracking: This kind of mold is easy to crack earlier than usual mainly due to following reasons:
a. EDM machining will produce steel stress on the mold;
b. Hardness of ribs on mold insert is lower than usual;
c. Heat will concentrate in the ribs on mold insert during mass production.
Geneally, tempering will be applied to the mold after EDM machining; When production reaches 2000-5000 shots (depending on the mold dimension), the mold should be tempered the second time. The mold can be maintained in a common way after these two times of tempering, but the first two times are especially important.

b) UG for tooling design, and we can also accept and process the files from SolidWorks, ProE and CATIA;
c) Flow-3D for mold flow simulation, and now we are also studying EKK and Magma and hopefully will adopt in the future.
 
Tooling Material
ASSAB 8407 (Orvar Supreme) and ASSAB 8418 (Dievar) made by Uddeholm and imported by ASSAB Asia are the most frequently used materials for die cast mold insert, and ASSAB XW-42 from the same supplier is the most frequently used material for trim tool cutter. Original material certificates of purchase and heat treatment will be shipped together with the tooling we deliver to the customers.
 
T1 trial Success Rate
Over 95% of our built molds have been successful during T1 trial and then were directly put into mass production on our customer side, so sometimes some customers told us to immediately ship the tooling to them soon after manufacturing completed for some urgent projects.
 
Tooling Size
The smallest mold we've built was fit on 60T die cast machine;
The largest mold we've built was fit on 2,500T die casting machine;
The largest die cast machine we can access for mold trial is 3,200T;
The largest die weight we can handle is ≤ 15T;
The largest dimensions of mold we are able to build are as shown below:
a) Mold Insert: 900mm*1,600mm (designed and manufactured by Precisioner)
b) Mold Base: 2,000mm*1,500mm*1,500mm (cooperating with our mold base supplier)
 
Production Volume
Monthly: around 45 sets of mold (one set means one die casting die and one trim die)
Yearly: around 500 sets of mold (one set means one die casting die and one trim die)
 
Short Lead Time (from approval of the tooling design to T1 mold trial)
A) Estimated by mold size of longest side:
3-4 weeks: <500mm 
4-7 weeks: 500-800mm 
7-9 weeks: 800-1,200mm 
9-12 weeks: 1,200-1,500mm 
B) Estimated by die casting machine tonnage that runs the mold (by approximate statistics, in calendar days):
32 days: tonnage<500T
38 days: 500T<tonnage<800T
42 days: 800T<tonnage<1,600T
48 days: 1,600T<tonnage<2,500T
