Automated sand casting equipment can efficiently provide the regeneration of old sand, efficient rotor sand mixer, can mix a uniform sand for casting, automatic molding machine, Jolt squeeze molding machine according to the size of the sand, providing 45-100moulds/h, shot blasting machine according to the casting material and surface roughness index 8-10 minutes can complete a cabin The surface treatment of castings, the orderly operation of the foundry in addition to the hardware support of sand casting equipment, but also depends on the combination of soft power, sanzhuji combined with the characteristics of sand casting equipment and the actual operation of the foundry, made the following summary.
1、Management and control of the casting process
1.1 Raw material control
Raw materials into the plant to have a perfect inspection report, new suppliers of products first small batch trial, stable performance in line with the requirements before mass production, so that the first plant first use after the plant into the use
1.2 Moulding and moulding process control
Strengthen personnel training, improve product awareness, make penalties for product quality problems that should not have occurred, place process cards in the workshop, so that employees can have a basis, develop operation manuals, each time with the model sent to the workshop, mold storage manual to retrieve, check once a week the amount of resin curing agent added, the removal of sand and water vapor in the mold cavity, the use of the closing box positioning pin is normal, the trial production of new products to The trial production of new products should be operated in accordance with the requirements of the process card and work instructions.
1.3 Melting process control
Strengthen personnel training, improve product awareness, make pouring record sheet, so that each furnace iron pouring those products, product pouring temperature, product with the piece of test rod are available, some products need to be heat preservation hanging open box time sign, no special requirements of the casting to do first pouring first open box after pouring after the opening box
1.4 Shot blasting and grinding process control
Strengthen personnel training, improve product awareness, to achieve daily site clearance, daily scrap accounting, for the larger pouring mouth to cut first after knocking down, grinding process can not be done by brute force, new product grinding to be operated under the guidance of the team leader
1.5 Product size and inherent defects control
For new products, the first piece must be scribed to confirm the size, and cut anatomy if internal defects need to be checked; daily production of old products to achieve key size sampling, for products that have not been done for many months, the first piece must be fully inspected for size after production again.
1.6 Scrap analysis and problem countermeasures Do daily scrap cleanup, scrap analysis group to discuss and summarize the causes of scrap, immediately make countermeasures to prevent the same problem for a long time.
1.7 Strengthen the shipment inspection
Improve the awareness of shipping inspectors, strict gatekeepers, prohibit the factory of problem products, set up a reward and punishment system, the appearance of customer complaints about quality problems, to be taken seriously, do not ignore the appearance of quality inspection due to tight delivery time
2、Management of the foundry
2.1 Manage people
More communication with the production staff, more understanding of the work of the staff. Life difficulties, to make employees feel at ease in the plant, work comfortably, the factory is my second home
2.2 Management of equipment Make good equipment labeling, so that equipment inspection and maintenance records are available, especially important equipment that will lead to downtime to check weekly, important equipment parts must have spare parts, once the equipment is damaged immediately replaced
2.3 Inventory of raw materials
Budget the daily consumption of raw materials, for typhoons, heavy snow and other disaster-prone months to make a good inventory in advance, to prevent road transport delays resulting in production stoppages
3、Cost control
3.1 Cost of raw materials
Real-time attention to the rise and fall of raw materials, adjust the purchase quantity and time, try to avoid the high price range, more contact with other suppliers, to do more than three
3.2 Waste control in the operation process Make raw material receipt, especially some inconspicuous small parts more who should receive who sign, for some items of high value must be received by the team leader, part of the portable electrical appliances damaged must be replaced with new
3.3. Transportation cost control
Communicate more with customers, try to arrange suitable tonnage for one shipment, reduce half-truck shipment, etc., and contact nearby self-provided cars and freight units to calculate the best transportation plan.
3.4. Weekly cost settlement
Pre-settlement of cost once a week and summary calculation once a month, so that early detection and early treatment
