1.Pipe mould: steel tube, plum tube, flat tube, oval tube, fan-shaped tube, polygonal tube, single and double groove pipe, tube frame, special-shaped mould, etc.

2. Selection: To produce first-class pipe mould, we must have first-class raw material. We choose hign-quality tool steel Cr12mov as raw materials, mouild steel Cr12mov material set high wear resistance, toughness, resistance to high pressure, high hardness, hard quenching.

3. Maching process: Raw materials- materials testing- exercise- saws- turning- drilling- turning- CNC precision turning- grinding- quenching- hardness test- internal and external grinding- test- boxing.

4. Features: Mature manufacturing process, experience and standard production management achievements leading provider of technology per crown. CNC machining of Japan, high precise; 10 years experience in RD, the fingerprints, mechanical pattern, on the corner, concave angle phenomena, and to form tolerance of roundness in les than 0.05mm, square tube on the angle does not exceed ±0.05mm.

Our company

Established in 1994, Jinan Jinpin is a composite company which can design and manufacture high frequency tube welding equipments, rollers, ferrite rods and cold roll forming equipments. Its main

products are various types of high frequency tube welding equipments, cold forming steel units,

ferrite rods, welded pipes, cold bending moulds and magnetic rollers for hot galvanizing line etc.

The company has three branches with a total staff about 200 people. It has strong technical strength

and processing capacity. The high chromium alloy, which is the wear-resistant materials, developed

by the company independently obtained national patent, and has been successfully applied to its

rollers manufacture. The rollers’ service life is 1.5 times of the common ones. The high frequency

tube welding equipments, researched and developed by itself , have automatic adjustment function,

need not to replace the rollers in the rough forming section. Time , effort and cost saving achieved.
