Plastics mold

PL part deburring, wear part

BL-01 Base material hardness is about HRC44~45 and you want to adjust the cladding hardness.

BL-02 Base material hardness is about HRC60 and you want to make cladding hardness close to it.

BL-03 Excellent characteristic and good match with precipitation hardening series such as NAK

BL-04 Good match with staingless steel such as 420J2. (High hardness after hardening)

BL-05 Chrome molybdenum series with toughness and you should use when base material is over HRC30.

BL-06 Chrome molybdenum series with high toughness and best to use when base material is less than HRC30.

BL-07 High toughness and excellent in weldability and use when needed the hardness HRC40. (SCM improved ver.)

BL-08 Excellent in grindability and weldability, applicable to clad welding for carbon steel and SC series.

Mirror surface

BL-04 is suitable for super mirror surface application type such as forming the light disc and lens, and contributes to customer's production improvement.。

BL-03 can be applied for the wide range of uses such as mirror surface application type forming the OA devices and cellphones.

BL-07 is widely applied for the mirror surface application type forming the home electrics parts and automobile parts.

Super minute welding

BL-02 φ0.1mm is most suitable for the mold for connector forming with HRC60, and makes finishing processing easier.

Diecast mold

Heat crack

(1) Adjust the base material by melting and digging by laser light.

(2) Underlay by RL-03 and clad weld close to the finishing surface.

(3) Clad weld by RL-04 above the finishing surface.

(4) Complete after finishing.

*In case you can't dig in by laser light, please process the edge preparation by Leutor etc. and clad weld.

*Repair can be done by RL-03 or RL-04

Large crack

(1) Please remove the crack by edge preparation by Leutor etc.

(2) Underlay by RL-03 and clad weld close to the finishing surface (about 0.5mm~1mm under)

(3) Clad weld by RL-04 above the finishing surface.

(4) Complete after finishing.

Dissolved loss

(1) Adjust the repaired part by air shot by laser light

(2) If you require the hardness, select RL-01 or RL-04. If you require the toughness, select RL-03 and clad weld.

(3) Complete after finishing.

Stress corrosion crack

(1) Please remove the crack by edge preparation by Leutor etc.

(2) Clad weld by RL-03

(3) Complete after finishing.

*Depending on the condition, it might be difficult to stop the water leakage.

Press mold

Chipping

You can process the excellent welding by using YL-01 in case you need more than 0.5mm for clad welding height.

If the clad welding height is less than 0.5mm, YL-04 is recommended.

Truing-up

YL-02 is suitable for the worn-out of punch and die, and it can be used widely.

Adjustment of the corner and clearance

We suggest to use YL-01/YL-03 for the case clad welding height of the corner is more than 0.5mm.

In case the clad welding height is less than 0.5mm, YL-04/YL-05 are capable of the repair of fine chipping.

In case the clad welding height of the corner is less than 0.5mm, YL-04/YL-05 are recommended as the toughness is high and it hardly generates the heat crack.
