Applications

Industries Served

How our rollers are typically applied across industries — the process challenge, the usual approach, and what to specify when you inquire.

Plastic film extrusion & lamination

Process challenge

Uneven cooling after extrusion often causes thickness variation, curling or inconsistent surface gloss; lamination needs a stable, even temperature to keep bonding quality consistent.

Typical approach

A spiral circulation cooling roll is commonly used to remove heat, with a thermal-fluid roll providing stable heating. The surface can be given a standard or mirror finish depending on the required appearance.

Key points when specifying

Cooling or heating, and the medium (water / chilled water / thermal fluid)
Face diameter, face width and line speed
Surface treatment (standard or mirror within Ra 0.02mm)
Temperature uniformity required (about 2°C on a 4-metre roll)

Applicable products

Spiral Circulation Type Cooling Roll / Thermal-Fluid Heating Roll、Vacuumed Ultra-Heat-Conductor Filled Electric Heating Jacket Roll

Rubber calendering

Process challenge

Rubber calendering is sensitive to both roll temperature and hardness: uneven temperature affects compound flow, while insufficient surface hardness shortens service life.

Typical approach

A thermal-fluid hole-drilled roll brings the medium closer to the working surface for better temperature uniformity, and the surface can be medium-frequency hardened for wear resistance. Where a plant thermal-fluid boiler exists, it can be connected directly to save electric heating.

Key points when specifying

Working temperature and thermal medium
Surface hardness (medium-frequency up to HRC54–58, 5mm deep)
Grinding accuracy (within 0.005mm under special requirements)
Roll dimensions and journal specification

Thermal-Fluid Circulation Type Hole Drilled Roll、Spiral Circulation Type Cooling Roll / Thermal-Fluid Heating Roll

Non-woven gluing & hot embossing

Process challenge

Gluing and hot-melt spot coating on non-woven fabric require consistent pattern transfer and temperature control; the pattern type directly affects glue volume and hand feel.

Typical approach

A stainless steel embossing roll provides diamond, cross or plain patterns, typically combined with a heating roll to hold process temperature.

Key points when specifying

Pattern type (diamond / cross / plain)
Working temperature and heating method
Roll dimensions and line speed
Material (SUS stainless steel)

Adhesive tape slitting & die cutting

Process challenge

Slitting and die cutting demand high surface hardness and roundness: insufficient hardness accelerates wear, while poor accuracy leads to uneven cuts.

Typical approach

An ultra-hardened anvil roll is commonly used as the counter roll, heat treated for high surface hardness while retaining toughness; a mirror finish can reduce sticking.

Key points when specifying

Surface hardness (up to HRC65–67 after heat treatment, 3–5mm deep)
Grinding accuracy (within 0.002mm)
Mirror finish (within Ra 0.02mm)
Roll length and journal fit

Applicable products

Ultra Hardened Anvil Roll、Die Cutting Roll

Flexible PCB & hot-melt lamination

Process challenge

Laminating flexible printed circuit boards and PVC film demands tight temperature uniformity, and the environment often restricts installing heat exchangers, pumps and piping.

Typical approach

A vacuumed ultra-heat-conductor electric heating jacket roll transfers heat internally, requiring no external heat exchanger, pump or rotary joint. It is compact and suitable for cleanroom environments, and the surface can be coated with VITON for higher temperatures.

Key points when specifying

Working temperature (VITON coating up to 200°C)
Surface temperature variation required (about 2°C)
Roll dimensions
Whether cleanroom conditions apply

Applicable products

Vacuumed Ultra-Heat-Conductor Filled Electric Heating Jacket Roll

Steel hot & cold rolling

Process challenge

Rolling subjects the roll surface to high contact stress and wear, demanding hardness, toughness and dimensional accuracy together.

Typical approach

Quenched-and-tempered alloy steel with heat-treatment hardening balances surface hardness and toughness, finished by precision grinding for dimensional accuracy.

Key points when specifying

Surface hardness and depth (HRC65–67, 3–5mm)
Grinding accuracy (within 0.002mm)
Roll dimensions and length (up to about 4000mm)
Balancing and hydrostatic test requirements

Applicable products

Ultra Hardened Anvil Roll
