Texas Continental Shelf Petroleum Engineering Technology Co., Ltd. is affiliated to Sinopec Petroleum Engineering Technology Research Institute. It is a high-tech enterprise that integrates research and development, production, sales and service of petroleum downhole tools and oilfield chemical additives. It has a history of more than 30 years. The company has strong R&D strength, complete production facilities, and advanced detection methods. The products cover domestic land and offshore oil fields and are exported to more than 30 countries such as the United States, Canada, and Russia. They enjoy a good reputation both at home and abroad. The company also drafted and revised 17 national and industry standards. It has completed more than 60 key scientific research projects at or above the provincial level and has won nearly 30 major scientific and technological achievement awards. Obtained 46 patents.
The hot air circulating oven ordered by Texas Continental Oil Company was 3800mm, 6000mm and 3500mm in width, depth and height respectively. The working temperature can be adjusted between 80~130°C, which is more favorable for manufacturers to adjust according to different materials. Materials, the general configuration of the oven (inner and outer walls of stainless steel, carbon steel skeleton). And this equipment is a fully automatic equipment. After the time is set, it can be operated by nobody. After the time is up, the equipment will be automatically shut down and the temperature in the box can be displayed in real time.
Characteristic of zinc die casting products:
1. High specific density, more strength than plastic injection molding.
2. Good casting performance, Producing complex shape and Thin-walled precision die casting
parts,
the surface of Zinc Die Casting part is smooth.
3. Easy do the surface treatment: Plating, powder coating, Painting.
4. Do not attract iron when Melt and die casting, do not corrosion Zinc Die Casting Mould and Non-stick mold.
5. Have good room temperature mechanical properties and wear resistance.
6. Low melting point, Melts at 385℃, more easily forming than aluminum alloy die-casting molding.
M Domestic commonly used die-casting zinc alloy material performance:
The traditional die-casting zinc alloy: No.2, No.3, No.5, No.7. ZA8 Currently the most widely used is zinc alloy No.3.
The application of commonly used zinc alloy:
No.2: It is used to those mechanical fittings that have special need in mechanical capability, and need high rigidity and normal dimension and precision.
No.3: Good liquidity and mechanical properties, and the best combination of mechanical properties, casting properties and economical. It applied to the die casting part which the mechanical strength requirement is not high. Such as toys, light parts, decorations and part of the electric parts.
No.5: Good fluidity and good mechanical properties, high wear resistance. It applied to the zinc die casting part which has requirements of mechanical strength. Such as auto parts, mechanical and electrical parts, machinery parts, electrical components.
