For example: stainless steel staircase handrails, anti-theft doors and windows, electric heat pipes, etc. 2. Product use process: welded pipe die...

1. Welded pipe mould

Welded pipe molds mainly include: round pipe molds and square pipe molds. According to the needs of different customers, we specially design and manufacture various special-shaped molds: plum blossom pipe molds, round head flat pipe molds, elliptical pipe molds, fan-shaped pipe molds, and octagonal pipe molds. It is used for the production of stainless steel pipes and carbon steel pipes for decoration, products, industry, household appliances, etc. This series of units can produce round pipes, square pipes, and rectangular pipes after molding, and can also produce elliptical pipes, semi-circular pipes, plum blossom pipes, etc. Various shaped tubes. Such as: stainless steel stair handrails, anti-theft doors and windows, electric heating pipes, etc.

 

2. Product use process:

The company's molds are used on the company's pipe-making machines, and there is no need for professional mold-adjusting masters to adjust molds, which greatly reduces labor costs and improves pipe-making efficiency.


3. Product features:

According to different pipe types and materials, the most reasonable forming design principle is adopted, Baosteel, Taigang Cr12MoV/imported SKD11 high-quality mold steel is selected, and the overall hardness of the mold can reach about HRC64° after high-precision CNC machining and vacuum air quenching and hardening; In the process of pipe making, the pipe forming stability is good, the pipe making efficiency is high, and the steel pipe will not be strained or nailed.
