Due to differences in materials and structural design, pulleys have multiple load-bearing levels. Different selections should be made based on different profile series, sizes, structures, and fan weights. Select according to the type of profile: ordinary aluminum pulley or broken bridge pulley; Divided into window pulleys and door pulleys, window pulleys can generally use single pulleys, while door pulleys can generally use double pulleys. The main difference between the two is that the overall load-bearing capacity of the pulleys is different; Select according to the size of the profile cavity: pay attention to the installation position of the pulley, profile size (K, G, G1), and slide rail size, and choose a matching pulley.
The inner and outer shells are made of stainless steel, which has better corrosion resistance; The wheel material is M250S, which has better wear resistance
Crescent locks are applied to sliding doors and windows. Crescent locks not only serve as switches, but also play a role in anti-theft to a certain extent. Crescent locks can generally be hung at 180 degrees, and there are various types of crescent locks. Crescent locks have long and short handles, and there are many varieties. The regular color is black, white, or silver, but different colors can be made according to customer needs. High quality crescent locks can be classified into aluminum alloy, zinc alloy, and zinc aluminum alloy based on their weight. The matching lock hooks are made of stainless steel material.
Injection molded part
It is a variety of injection molded parts produced by injection molding machines, including various rubber corners, plugs, drainage covers, corner protectors, glass gaskets, etc. The main materials are polyethylene, polypropylene, EPDM rubber, silicone rubber, TPE rubber, etc. The choice of plastic parts mainly depends on the type of plastic (thermoplastic or thermosetting), initial shape, and the shape and size of the product. Injection molding is generally used to produce injection molded parts, among which extrusion and injection molding are the most commonly used and basic molding methods.
Having the ability to develop aluminum alloys, we can match alloy combinations according to different performance requirements of customers, which not only meets their needs for product performance and lightweight, but also achieves cost savings.
Based on the precision and performance requirements of the product, we can independently design the production process route, which greatly improves the performance of the welded parts and ensures the dimensional accuracy of the assembly.
Having the ability to develop and modify extrusion and stamping molds, reducing mold development costs.
Having automated extrusion production lines and CNC production lines reduces labor costs.
We have advanced production lines for surface treatment such as oxidation, electrophoresis, and painting, which can meet different customer requirements while reducing equipment investment costs.
The group currently has over 150 extrusion production lines ranging from 600 to 10000 tons, with an annual production capacity of 800000 tons, of which 40% are over 2000 tons. Including various specifications of extruders ranging from 500 tons to 10000 tons, the Sixth Factory is mainly dedicated to the production of industrial profiles and automotive lightweight profiles, with sufficient production capacity to meet customers' extrusion needs of various sizes and specifications.
We have established a national level standardized testing center, which has been accredited by the China National Accreditation Service for Conformity Assessment (CNAS) and accredited by the China National Accreditation Service for Conformity Assessment (CMA); There are 13 high standard laboratories jointly established, including chemical analysis laboratory, metallographic laboratory, mechanical performance laboratory, physical performance laboratory, spectroscopy laboratory, salt spray laboratory, and aging laboratory. Key instruments and equipment are imported from countries such as the United States, Germany, and Israel.
The aluminum extrusion experience of the group has a development history of more than 20 years. After years of verification and accumulation, a rich database of data and experience has been formed, including product databases, design standards, analysis specifications DFMEA、PFMEA、 Control plan, process validation data, etc.
