The heating roller offered by Shanghai Donghui Roller Machinery Co., Ltd. is manufactured from forge alloy steel grades 20# and 45#, specifically 42GrMo and 38GrMoAI, and is heat‑treated to achieve a hardness between HRC55 and HRC58. The roller features a single‑layer, multi‑layer screw or Z‑type inner structure, and its external surface is coated with a hard chrome layer using a Dupont formula, resulting in a compact chrommantel with strong adhesion. The supplier notes that the unit is designed for precise temperature‑difference control during operation.
Forge alloy steel of the 20# and 45# grades is commonly used in industrial heating equipment because of its balance of strength and wear resistance, and a hardness of HRC55‑58 aligns with typical standards for rollers that experience cyclic thermal loading. Hard chrome plating is a standard protective finish in the sector, providing corrosion resistance and extended service life under high‑temperature conditions. While the listed inner structures are specific to this maker, similar rollers often employ multi‑layer screw designs to improve thermal uniformity.
These rollers are typically integrated into continuous‑film laminators, hot‑press lines and other thermal processing machinery, making them attractive to manufacturers of packaging films, automotive interiors and printed electronics. Buyers usually arrange bulk shipments under FOB or CIF terms and request documentation such as material test certificates and coating thickness reports before finalising the contract. The supplier does not disclose a minimum order quantity, so interested importers should contact the company directly to confirm trade conditions.

Before placing an order, verify the material grade and hardness by requesting a mill test report and a Rockwell hardness certificate. Ask for a coating thickness measurement to ensure the hard chrome layer meets the typical ±10 µm tolerance. Confirm that the inner‑structure design (single‑layer, multi‑layer screw or Z‑type) matches the specifications of your production line.
Discuss logistics early: ask the supplier which Incoterms they can provide, typical lead times for production and shipment, and whether they can arrange container loading at Shanghai ports. Clarify payment terms, such as a letter of credit or advance payment, and whether any partial payment milestones are available. Because the supplier’s response rate is currently zero, maintain written communication and consider using a third‑party verification service.
Plan quality inspections by arranging a pre‑shipment audit or requesting third‑party test results for material composition, hardness and coating adhesion. Ensure that the supplier can supply the required documentation, such as a conformity declaration and any applicable national standards certificates. These steps will help minimise risk and ensure the heating roller meets your operational requirements.
