①Capability
Manufacture more than 1,600 core parts
for die-casting dies per day
Monthly Production
Core pin
42,000 pieces
Insert 100 pieces

②Precise cooling hole
Φ1.5mm(.06”) x length 280mm(11.02”)
Hole runout accuracy e.g.
Φ2.1mm(0.83in) x depth 278mm(109.45in)
⇒ Hole tip concentricity 0.16mm(0.06in)

③3DP technology for toolings
Free structure of conformal cooling
→ Longer product life
and improved quality of cast products.
e.g.) Shot life increased from 40,000 to 90,000.
80% reduction of maintenance time.

④Special coatings
Arrange all special coatings available including
PCVD coatings (#1&2)
News
New coating “STELLA coat” just developed and release soon!
Problem Measure
Seizing for pins ⇒ Lumena coating
Seizing for inserts ⇒PCVD-TiAlSiCNO
Galling for bushing ⇒ Sulphonitriding
Galling for sliding pins ⇒ TD
We can propose suitable coating for each case.
Analysis Service
Analyze your problematic core pins and Investigate causes from various
viewpoints.
Report measures and propose ideas to solve the problems.
【 Examples of proposals 】
Problem Seizure occurred on core pins near the gate after
1,000 shots.
Before proposal H13 +Gas Nitride
Our Proposal Change of cooling hole design
+ Change of coating to Thick layered PVD
Result Seizure resolved and life extended to 20,000 shots!

Actual sample case#2
Actual sample case#3
Castec Proposal :Change coating to PCVD-TiAlSiCNO.
Actual sample case#4
Core pin : Head bold pins (Low pressure diecasting)
Problem : Errosion, bent and breakage
Shot life : 2,500 shots
Specification : H13, Heat treatment, no coating
Proposal :
Material : Change to W360
*As we obseve material softening, high temperature strength
material is better in this case.
Hole desing change : Hole dia.3.5
change to Dia.2.0 to enhance
strength.
Hardness : HRC 57
Coating : Balinit Formera (PVD)
*Heat, wear, soldering resisitant coating.
Result : Life extended to 8,000 shot
and reduced die maintenance time.
