How Dongguan Precision Casting Improves Production Efficiency

Dongguan Precision Casting: How to improve production efficiency, let us take a look!

In order to improve the production efficiency of goods, modules were accidentally lost during the casting process. Processing not only requires employees' time, but also the raw materials of the modules. But now, China is promoting energy-saving and environmentally friendly production. This has been affected by policies. Currently, many precision products in Dongguan The development plan of the foundry industry is changing towards a green and environmentally friendly direction. Which methods often appear in die-casting energy-saving and environmentally friendly manufacturing? The following is a summary of these 6 points.

1. Save raw materials and strive for recycling. Each raw material requires energy to produce and process.

2. Our company is a company engaged in die-casting industrial production and processing. The total output of each forging combustion controller is about 500 tons. Due to the large total value of the enterprise, the kiln working hours are long. The kiln body itself can be expanded to 1 ton casting, which greatly Reduced energy consumption.

3. Improve management capabilities and reduce the scrap rate. For example, in an investment casting factory with a total production capacity of 500 tons, each reduction in the scrap rate is equivalent to the production of more than 50 tons of investment castings. Calculated based on energy consumption, kgee\/t can be Save 20 tons of standard coal. In other words, the energy consumption of one ton of precision castings can be reduced by 4 tons of kgee.

4. Select the structure, optimize the design and manufacturing process, and improve the yield of the precision casting manufacturing process. In order to ensure the quality of precision castings, the concrete spraying system can be modified to a heated insulation nozzle, which generally can increase the export rate. If the export growth rate increases from 60 70, energy consumption will be reduced by 14.3%.

5. Choose high-density molding machines and current key production processes to avoid low casting quality and Z feed speed. According to practical experience, high-pressure design products can reduce casting quality to 3-5, while manual design products and general industrial equipment design products .The feed speed can be maintained at 2-2mm. Reducing the net weight can not only save energy in the die-casting production line and protect the environment, but also reduce energy consumption in later production.

6. Die casting adopts energy-saving and environmentally friendly production technology, and rationally organizes production and processing. If hard resin sand or surface dry casting is used instead of clay sand dry casting, the energy consumption of blowing metal castings can be saved. Strict seasoning depends on the appropriate composition of precision castings .The application of growth plan removes the annealing process of pure graphite containing white spots or hard particles under casting specifications. In order to promote the promotion of gray cast iron in the market, the breaking strength of gray cast iron is less than or equal to 12. Try to select the frequency of wave surge current During the VSL manufacturing process, stress reduces thermal aging in the field.
