Steel belt surface treatment technologies

DYMCO's surface treatment technologies support steel belts and its various functions.

Fluoroplastic coating

• Non-stick release;
• Heating process such as UV irradiation and sterilization, drying and heat sealing;
• Image inspection process using reflection-free surface of the coated belt

Photo etching

• Offers remarkable cost reduction for an initial setting because photo etching does not require high tooling charge.
• Without burrs, distortion and work hardening photo etching realizes excellent surface flatness.

Electro-forming

• Highly accurate perforation of micron order
• Excellent hardness of Hv450 to 550
• Smaller hole diameter than belt thickness

Micro press work

• Super minimum tolerance of perforation
• Smooth inside wall of a hole like mirror finish
• Various hole shapes
• Sharp edge

Plank minute perforation on thick belts

• Super high speed processing: max 4000 holes/second
• Aspect ratio more than 10 (ratio between belt thickness and hole diameter)
• Processing on three dimensional objects
• Diagonal holes

Thermal Spraying

• This process sprays thermal spray material to pulleys or material surface.The outcome rough surface offers higher friction coefficient and often works as nonskid between metals.

Mirror polishing

• Mirror finish on stainless steel
• Available for plates, strips and endless belts.

Punching

• Punching holes with various shapes and patterns on a metal board

Diffusion joint

• Minute holes by building up thin etching plates
• Thick plates available through the multilayer structure
• Possible continuous operation under high temperature
• Easy washing and drying due to smoothness and no clearance between layers

Reforming processing

• The hardened layer of 20~60 microns is generated on material surface.

Bandsaw substrate

• Open stainless steel strips are welded to be endless and diamonds are electroplated along edges.
• These bandsaws cut hard material.

Band knife

• Sharp edge is given to a metal strip. This cuts various material.
• It can be endless.
