Bengbu City Long Hua die casting machine factory was founded in 1982, is a professional R & D, production, sales of die-casting machine, die casting peripheral equipment, die-casting mould of high technology enterprises
On December 10, 2005 Anhui provincial Party secretary Comrade Wang Jinshan, to Long Hua pointed out that the strengthening of science and technology, establish a brand, pay attention to talent, independent innovation"
Longhua was awarded the national science and technology project 2 (National Torch project, major national science and technology projects a). Longhua die-casting machine products has won: "first national Ministry of machinery, products Buyou title", "casting machinery industry standard demonstration unit", "China product quality association member units", "Shou contract re credit enterprises", "import and export Mianjian products", "Alibaba depth inspection factory integrity enterprise", "Anhui Province high technology enterprise" honor.
Long Hua die casting machine products, are to achieve computer aided optimization design (CAD/CAE), hydraulic system using the German technology, Japan's hydraulic technology, the program uses PLC man-machine interface system, human nature, the operation is more simple
Longhua after 35 years of unremitting efforts, long China research and development of magnesium alloy (aluminum) energy saving vacuum die casting machine was awarded the "Anhui Province high-tech projects progress award" a, and gradually won the State Intellectual Property Office nine high-tech patent: a high-tech invention patents, eight Gaoke technology and practical patents.

1. Double proportional control (electric regulation of pressure and flow, with a multi-level pressure and speed control as well as low pressure die close protection functions).
2. Dual circuit design (air injection and pressure building are separately designed without mutual interference and fault occurrence).
3. Four-stage (multi-stage) injection system:
A.Maximum speed> 8M/s (6M / s for those more than 2000T), which can effectively control the filling time and casting formation, in addition to unique braking and uniform acceleration injection function that can effectively prevent flash and allow more flexible injection process.
B.Minimum speed 0.1-0.7M/s, which can be precisely controlled to prevent air invasion from causing air trap.
C.Pressure building time ≤15 M/s, which allows to change pressure building speed according to process requirements, strengthening the casting density without causing product distortion.
D.Dry cycle time is reduced by more than 15%; Oil pump flow increases by more than 20%; Cooler capacity is enhanced by more than 100%; Proportion of conforming finished products rise by 100%; productivity is improved by 20% as compared to the past.
