Rubber is produced with imported raw rubber. The main properties of the product are: non-toxic, tasteless, environmentally friendly, aging and high temperature resistant, heat-resistant, stable performance, good performance in summer and winter. The steel frame is three composite, not easy to deform and contract, and is firmly assembled with good sealing performance. EPDM sealing strip is used for doors, windows and curtain walls. The product has good elasticity, migration resistance, and can effectively block noise, dust and wind.

Copper clad steel wire is easy to leak, wear-resistant and corrosion-resistant. The mesh section is trapezoid. The gap is narrow at the top and wide at the bottom. It is a screen bar made of stainless steel wire by cold rolling. The support bar is welded by the automatic screen mesh production equipment. The screen seam is uniform, the welding quality is stable, the opening rate is high, the service life is long, and it has high strength, steel degree and bearing capacity. It can be made into a steel screen filtration device of various shapes.

Basic process of medium and high frequency annealing of stainless steel: adopt the medium and high frequency induction heating method to rapidly raise the temperature of stainless steel to about 1050 ℃ (the specific temperature is determined according to the customer's requirements), and then transfer it to the ammonia decomposition atmosphere protection pipe to rapidly cool to below 100 ℃, which can realize bright solid fusion annealing. The heat preservation method adopts the unique inductor specially designed for stainless steel annealing, with a total length of more than two meters, convenient and reliable operation. Eight
