Effect cases

Y-coat's progress in different processes

Below is to introduce Y-coat's effect cases.
To meet your needs and wants, we will recommend best process based on our knowledge and experience in the surface treatment industry. Please contact our sales staffs for more information.

Effect in low temp. forging process  Case1

Theme

Longer and stable usable life for mold hole press

Name:Mold hole press Material:Super hard V30 equivalent
Work piece:SCM Size:20×25mm
Surface:CVD-TiCN  
Problem * When it was processed with CVD-TiCN, the usable duration was not stable (100~150,000) due to the damage on the mold hole punch itself.
Countermeasure * Changed to TiCN by Ion-plating method,which gives constant and stable compression pressure to plated film.
Result

* Usable life became constant. Reduction in total cost.

Effect of having stable compression pressure.

Effect in low temp. forging process  Case2

Theme

Longer life for teeth-shaped press

Name:Teeth-shaped press Material:SKH51
Surface:TiCN  
Problem * Durability of 10,000 shots due to abrasion.
Countermeasure * Add nitriding process (Nitriding+TiCN) for abrasion resistance.
Result

* It will now last 40,000 shots.

Multi-process to increase durability

Effect on metal plate pressing machine Case1

Theme

To gain longer durability on Body-peeler cutting process

Name:Cutting blade Material:SKD11
Work piece:Plated steel plate Thickness:1.4mm
Surface:TiC(CVD)  
Problem * With TiC(CVD) process, cracks appeared after 8,000 shots.
* Re-process at welded part was not possible.
Countermeasure * Welding repair is damaged area.
* Coated Type V which has same hardness as TiC (Hv 3,300)
Result

* Lasted 30,000 shots
* Able to re-use after welding repair

Increased toughness of film mitigated chipping. Able to coat on top of welded area.

Effect on metal plate pressing machine Case2

Theme

Longer durability in SUS treatment

Name:Press die Material:SKD11
Work piece:SUS40 Thickness:1.5mm
Surface:TD treatment  
Problem * Need polishing maintenance once a month, due to scratch and cracks caused by SUS dusts.
Countermeasure * Use CrN to prevent SUS welding.
* Use multi-process with Nitriding (Type KR) to prevent scratches and cracks.
Result

* With TD treatment, once a month maintenance was needed, but with above process there is no need for maintenance for 6 months.

Cracks do not appear, due to CrN's resistance against welding and cracks.

Effect on metal plate pressing machine Case3

Theme

To increase durability of thick plate press die

Name:Press die Material:SKD11
Work piece:SPC440 Thickness:6.0mm
Surface:TD treatment  
Problem * Life duration was not consistent.
* Cracks at early stage, need for maintenance.
Countermeasure * Changed to PVD (Type KX) which processed by low temperature.
Result

* Able to shot 19,000 times (6,000 shots only with TD)
* Less dust that damages work piece, leading less maintenance required.

Less shape change due to low temp. process. Multi-process lead to increase in crack resistance
