常见问题解答
Why stress relieve before finish machining?
Machining leaves residual stress that pulls the part out of tolerance when material is removed. Relieving stress between roughing and finishing keeps the final dimensions stable.
What hardness can you achieve?
Tool steels reach 58 to 62 HRC after hardening and tempering, while case hardening produces a hard surface with a tough core for impact resistance.
How do you control distortion?
By using controlled heating and cooling rates, supporting long parts during the cycle and, where necessary, leaving grinding stock that we remove afterwards.

Anodizing
Type II and Type III anodizing for aluminium: clear, black and colour finishes with improved corrosion and wear resistance, thickness from 5 to 50 µm.
Hard Anodizing
Type III hard anodizing builds a 25-50 µm ceramic-like oxide layer with up to 500 HV surface hardness for wear-critical aluminium parts.
Bead Blasting
Glass bead blasting for a uniform satin finish on metal and plastic parts. Hides tool marks, prepares surfaces for coating and gives a premium matte look.
Sand Blasting
Sand blasting for surface cleaning, descaling and roughening. Removes rust, scale, old coating and oxide before welding, painting or bonding.
Polishing
Mechanical polishing to mirror and optical finishes: Ra down to 0.05 µm for mould cavities, light guides, medical parts and decorative surfaces.
