Precision Gear Manufacturer for Demanding Industrial Needs

Raydafon moulds custom plastic helical gears in POM and nylon at its own factory in Ningbo, China. Standard tooling covers module M0.1–M2.0, bores from Ø1.40 mm to Ø3.05 mm, outer diameters Ø10–Ø50 mm (up to Ø120 mm on custom tooling) and face widths 2.0–10.0 mm, with a working temperature range of −30 °C to +100 °C. Because the tooth form is produced in the injection mould rather than cut, helix angle and profile stay consistent across the batch, and the gears run self-lubricating and quiet — measured noise is about 20% lower than equivalent spur-gear drives in the same application. Glass-filled grades are available where higher torque or stiffness is needed, and machined plastic or metal gears are quoted where moulded plastic cannot meet the duty.

Raydafon is a China-based OEM manufacturer and supplier of brass worm wheels for worm gear drives in engineering machinery, metallurgical equipment, medical devices, shipbuilding and automated warehousing. Standard production uses ZCuSn10Pb1 tin bronze, hardness HB≥80, wear resistance about 30% higher than ordinary brass. The gear is processed through five precision steps — casting, rough turning, fine turning, hobbing and grinding — reaching tooth surface roughness Ra≤1.6μm and meshing error below 0.05 mm with the matching worm. Transmission efficiency is about 15% higher than the national standard, and self-lubricating performance reduces oil dependency. Continuous 5000-hour operation test shows wear rate below 0.01 mm per 100 hours. Standard sample: module 0.5, 20 teeth, teeth diameter 11.2 mm, height 12 mm, outer diameter 11 mm, bore 4 mm, weight 16 g. Custom module, teeth number, outer diameter from 50 mm to 300 mm and material grade are supported. Delivery is around 15 days for standard orders. Send drawing, material grade, quantity and destination port for a fast quotation.

Raydafon, a well-known chinese manufacturer, has created the Duplex Worms Gear with high cost performance by relying on the unique craftsmanship of its factory masters, and has become a trusted supplier for machinery and automation companies at reasonable prices. This worm gear is made of high-strength copper alloy and alloy steel, and has undergone seven fine grinding processes. The bite is tight and does not slip, and the transmission efficiency is 15% higher than that of ordinary products; the two-stage transmission design doubles the torque while keeping the noise lower.

Raydafon manufactures spiral bevel gears for right-angle drives in its own factory in Ningbo, China. The curved tooth line keeps two or more teeth in contact at every moment, so the drive runs more smoothly and quietly than a straight bevel pair of the same size and carries more torque for its dimensions. Standard modules run from M3 to M12 with precision grades DIN6 to DIN9, produced to ISO, DIN, ANSI, JIS or BS. Materials include alloy steel, C45, stainless steel, brass, copper, aluminium and POM, with surface treatments from zinc and nickel plating to black oxide, Geomet and Dacromet. The pinion can be cut with as few as five teeth, allowing a large reduction ratio in a single right-angle stage, and tooth flanks can be ground after heat treatment for the higher precision grades. Gears are supplied as matched pairs with the contact pattern checked before dispatch. Send your drawing or sample for a quotation within 24 hours.

Raydafon manufactures plastic bevel gears in Ningbo, China, moulded in POM and nylon for right-angle drives. Standard ratios are 1:1, 2:1, 3:1, 4:1 and 5:1; pitch modules M0.25 to M1; tooth counts 10 to 60; bore diameters 3.0 to 10.0 mm; outside diameters 8.7 to 60.4 mm; operating temperature −40 °C to +80 °C. Part numbers include GB05M016, GB1M016, GB1M016BS, GB1M215030, GB1M215030BS, GB1M315045, GB1M315045BS, GB1M410040, GB1M410040BS, GB1M512060, GB1M512060BS, GB1M512* and GB1M512BS*. BS suffix indicates a brass insert and set screw. Important: GB1M512* and GB1M512BS* match only with the 60-tooth bevel gear and are not compatible with other gears. Moulded tooth geometry gives quiet, tight mesh; the polymer is self-lubricating and chemical resistant. Custom module, tooth count, bore, hub and material grade available to drawing; quotation within 24 hours.
