Zhoushan Ruihong Screw Manufacturing Co., Ltd. offers an industrial automobile gearbox designed for power transmission in a broad selection of configurations, including gradual, mutant, wave, barrier, double screen, shunt and separation types. The gearbox incorporates hardened alloy steel gears and a cast iron housing, providing durability for demanding processing of engineering plastics such as PA, PP, PC and many others. The design is suitable for OEM procurement and integration into manufacturing equipment that processes powders and pellets.
The gear set is machined from hardened alloy steel, a typical material choice for high‑torque transmission units, while the cast iron housing offers excellent vibration damping. Standard industry practice recommends a gear ratio range of 0.5 to 3.0 for flexible speed and torque conversion, and an oil‑bath lubrication system to maintain gear surface integrity. Typical mounting involves a flange with bolt‑on brackets, and the unit is usually supplied in export‑grade wooden crates with protective padding.
Target customers include manufacturers of plastic extrusion lines, pelletizers and compounding machines that require reliable torque conversion and speed regulation. The gearbox can be ordered with standard export packaging and shipped under common Incoterms such as FOB or CIF, subject to confirmation of minimum order quantities and lead times. Prospective buyers should request detailed technical drawings and material certifications to ensure compatibility with their specific line configurations.

When initiating a purchase, confirm the exact design type (gradual, wave, etc.), the selected gear ratio and the torque requirement for your line. Ask the supplier to provide material test certificates for the hardened alloy steel gears and the cast iron housing, as well as a dimensional drawing that matches your installation space.
The gearbox is typically shipped in wooden crates from the port of Zhoushan, and buyers should agree on Incoterms such as FOB or CIF before finalising the order. Lead times are usually between 25 and 40 days, but this should be verified with the supplier. Discuss payment terms, which may include a letter of credit or a 30‑day post‑shipment payment schedule, and clarify any minimum order quantity requirements.
Quality assurance should involve a pre‑shipment inspection covering gear tooth profile, hardness, and dimensional tolerances, as well as a functional run test under load. Request a full inspection report and, if needed, arrange a third‑party audit to verify compliance with industry standards. Documentation such as material certificates and a test report will help ensure the gearbox meets the performance criteria of your plastic processing equipment.
