Lost mold casting production line

Simple or simple

Usually 1 or 2 sets (for modeling) of three-dimensional shaking table, several -10 special sandbox, sandbox hoisting or sandbox simple conveyor belt roller (track) road, dry sand natural cooling or equipped with a simple sand cooling device, plus vacuum system and sand screening equipment.Flexible investment, cost 80,000-150,000 yuan, the production scale is generally 500-5,000 tons.This mode of production suits China's conditions, costs less and is faster.It is very popular among small and medium sized enterprises in China.These factories account for more than 90% of foam foundries in China.

Domestic type

Domestic production lines designed by mechanical, hydraulic, pneumatic and electronic control methods have many sandboxes ranging from 10 to 50;Equipped with sand cooling system equipment;The production scale is 20,000-30,000 tons per year, with investment ranging from 500,000 to 40,000 tons.There are about 30 such factories.Full function, full function, continuous operation, suitable for mass production, mass production.

Introduce abroad

In these factories imported from abroad, the investment is less than 10 million yuan, at most (cumulative) about 80 million yuan, generally between 40 million and 50 million yuan.

Layout principles

Vanishing die production line is generally divided into two areas: white area and black area.The white area has a relatively good working environment and is usually a separate workshop.The black zone is also an independent workshop.The main problem with epc production line layout is to master the following principles: equipment layout as compact as possible.Make the most of space.The connection distance between the main equipment and each auxiliary equipment should be minimized.In addition, the layout of equipment can be considered in combination with logistics channels and security issues.

The production process of epc is a large flow production line composed of several sets of equipment.Reasonable production line layout can save part of the cost generated by connection between equipment and equipment, reduce unnecessary project waste, shorten the distance of workshop logistics channel, improve production efficiency, reduce production cost, effectively use resources, and even extremely reasonable production line layout is conducive to the full play of the production process.(the distance between the white area after drying, the shape into the forming part, the distance from the intermediate frequency furnace in the black area to the casting line, etc.)

However, due to the foam polystyrene (EPS) is widely used in China, the special coating technology has not yet formed technology advantage, dry sand vibration technology and lost foam casting process is not mature, lead to many of the early companies, especially small and medium-sized enterprises, there is still no deep understanding to the understanding, so there will be a passive situation after another.Experts said that the domestic foundry industry still needs continuous efforts in order to better develop in the future.
