Punching Cable protectors are formed by bolts mounted in the connection pipe, for a variety of cables, control lines, chemical injection lines, encapsulation lines, etc, widely applied on cross-coupling, tubing, safety valve protection, completions, fixing, well repair and gauge completions. It provides a safe and quick way of conveying and securing downhole cables into a well-bore. The materials are stainless steel, carbon steel, and other materials for the client`s unique needs. It is convenient and multi-coupling compared to the other products; hence they are preferred by more clients. A hand caliper or hydraulic caliper is needed for field installation
Weifang JunLong Precision Casting CO., LTD., the main products are precision casting of carbon steel, low carbon steel, medium carbon steel castings, high carbon steel, alloy steel precision casting, high manganese steel, high chromium steel, high nickel steel, a variety of materials such as precision casting products. The parts are mainly used in precision casting of auto parts, forklift parts castings, precision casing of ship parts, precision casting of train parts, mechanical engineering, petroleum machinery, and mining machinery. Our products have been exported to more than 20 countries and regions worldwide. Our company has cooperated with our customers with the business philosophy of integrity, pragmatism, professionalism, and innovation, and won the unanimous praise of our customers.
The company covers an area of 30,000 square meters, with more than 200 employees,10 R&D personnel, and 12 quality control personnel. There are three production lines, two composite processes (i.e. silica sol + water glass), and one silica sol process. The annual output reaches 8000 tons, the enterprise has passed iso9001:2005 quality management system certification and passed the national environmental protection department approval, has the formal environmental assessment certificate, and is a household name of the green casting enterprise.
Our general manager makes all the assembly lines in the workshop according to practical experience. The product quality can be guaranteed while greatly improving the work efficiency and reducing the workload for the workers. By the end of 2015, all the workshops of our company had been automated production. For example, automatic wax injection machine, automatic silicon sol process robot, automatic silicon sol process wind main line, automatic water glass process assembly line, curing pool, and automatic pouring. Because they are all automated production, the quality of the shell is guaranteed in the early stage, Precision casting products with weights from 0.1KG to 500 can be completed. Products with wall thickness as low as 3mm. Products with complex shapes. The defects of porosity, sand holes, slag inclusion, cold insulation, shrinkage, and other casting defects are effectively avoided.
Are main products of our company adopt a complex process (silica sol + water glass), adopt low-temperature wax, four shell layers using silica sol process, three layers using water glass process, and composite process to produce a product that no matter from the surface finish, and internal quality and silicon sol process almost the same, the price is lower than silicon sol process, and water glass price. However, it's cheap, but the product is very rough, and composite technology products of good quality and low prices, the most suitable for large batches of products, can guarantee the quality of customer requirements and can guarantee a reasonable profit space, so, Our foreign customers have been cooperating with us for 8 years, and we have cooperated very well.
Inspection: our company has a special physical and chemical laboratory, with perfect inspection equipment (spectrometer, three coordinate measuring machine, metallographic analyzer, impact test machine, tensile testing machine, hardness tester, magnetic particle inspection machine, ultrasonic testing, etc.), can satisfy the customer different product requirements, and issue a corresponding test report.
Processing: we have two horizontal machining centers, a CNC machining center, a bench drill, a vertical drilling machine, a rocker arm drilling machine, a milling machine, a grinder, a planer, CNC lathes, and other all-round machining equipment.
