Six ways to save production in precision casting

As we all know, when casting parts in Dongguan Casting, carelessness will result in payment of mold parts. The generation of the reimbursement not only delays the staff's time, but also wastes the raw materials of the module extravagantly. However, nowadays, environmental protection and energy-saving manufacturing are advocated in our country, suffering from the harm of new national policies. Nowadays, the industrial layout of many precision casting plants will change to green and environmental protection. So what are the common methods of environmental protection and energy-saving manufacturing in precision casting? The following summary is in total There are 6 points:
1. Save raw materials and diligently recycle. Since all raw materials are produced and manufactured, energy consumption is required.
2,Precision castingThe company's industrialized manufacturing, that is, the output of each forging module is about 5000t. Due to the large production capacity of the company, the working hours of the furnace are long, and the energy consumption of the furnace itself for heating can be greatly reduced by apportioning the energy consumption of one ton of precision castings.
3. Improve the management ability and reduce the unqualified rate. For example, for a precision casting plant with an annual output of 5000t, every 1% reduction in the unqualified rate is equivalent to the production of 50t more precision castings. According to the energy consumption of 400kgee per ton, it can save 20t standard coal in one year, that is, one ton of precision castings. Casting reduces energy consumption by 4kgee.
4. Selecting reliability design and improving processing technology to improve the honor production rate of precision casting parts. Under the premise of ensuring the quality of precision castings, changing the pouring system software and applying hot heat insulation risers can generally increase the export rate. If the export rate can be increased from 60% to 70%, the energy consumption can be reduced by 14.3% .
5. Choose high compactness molding machine and its contemporary core-making technology to minimize the quality of castings and reduce the machining allowance. Practical experience High pressure modeling design can make the quality of castings 3%-5% easier than hand-made modeling design and general equipment modeling design, and the machining allowance can also be maintained at 2-3mm. Reducing the net weight not only makes the precision casting production workshop environmentally friendly and energy-saving, but also reduces the energy consumption of subsequent production and processing.
6. The precision casting adopts environmentally-friendly and energy-saving production processes, and effectively organizes production and manufacturing. For example, the application of self-hardening resin sand casting or the surface dry type instead of the clay sand drying type can save the energy consumption of air-dried metal mold casting; strict seasoning, clarification of the suitable components of precision castings, and the nurturing plan to take measures will be used in the as-cast state. Remove the white holes or hard spots on the castings to cancel the high-purity graphitization annealing process; promote the marketing of as-cast ductile iron, and stipulate that the elongation after fracture should be obtained in the as-cast state; use frequency pulse current as much as possible The vibration aging processing technology removes the thermal aging processing technology to reduce the ground stress.
Learning this will improve the company's high efficiency and save costs.
