铸造

  福州荣林机械有限公司的关联企业福建金大机械制造有限公司,成立于2019年07月,注册资本1000万元,是一家专门从事精密铸件生产的企业。

  金大机械采用的是熔模(消失模)精密铸造法,熔模铸造原理起源于我国商代中晚期的焚失法,到春秋战国时期失蜡铸造技术得到进一步发展,中国古代在青铜铸造上已经使用这种方法。金大机械将传统的工艺技术和现代科技技术完美的融合,形成了年产5000吨精密铸件的自动化铸造生产线及配套的水循环再利用和空气净化成套设备。

  金大机械的自动化铸造生产线采用IGBT(Insulated Gate Bipolar Transistor)串联谐振式感应加热电源装置,具有恒功率输出、熔炼速度快、节能、环保、无高次谐波干扰等特点。生产的铸件尺寸精度一般可达CT4-6;表面粗糙度一般可达Ra.1.6~3.2μm,加工余量少;铸件的一致性好;可以铸造各种复杂的铸件。

  熔模铸造技术的运用不仅铸件质量高,而且降低了员工劳动强度,提高了生产效率。消除了废气和粉尘排放,有利于环境保护,完全符合低碳经济的大趋势。

Fujian Jinda Machinery Manufacturing Co., Ltd., an affiliate of Fuzhou Longlife Machinery MFG Co., Ltd., was established in July 2019 with a registered capital of 10 million yuan and is an enterprise specializing in the production of precision castings.

Jinda Machinery adopts the investment precision casting method, the principle of investment casting originated from the incineration method in the middle and late Shang Dynasty in China, and the wax casting technology was further developed in the Spring and Autumn Warring States period, and this method has been used in bronze casting in ancient China. Jinda Machinery perfectly integrates traditional process technology and modern technology and technology into an automated casting production line with an annual output of 5,000 tons of precision castings and supporting complete sets of water recycling and air purification equipment. 

Jinda Machinery's automated casting production line adopts IGBT (Insulated Gate Bipolar Transistor) series resonant induction heating power supply device, which has the characteristics of constant power output, fast melting speed, energy saving, environmental protection, and no high harmonic interference.  The dimensional accuracy of the castings produced is generally up to CT4-6; the surface roughness is generally up to Ra.1.6~3.2μm, and the processing allowance is small; the consistency of the castings is good; and various complex castings can be cast. 

The use of investment casting technology not only has high casting quality, but also reduces the labor intensity of employees and improves production efficiency. The elimination of exhaust gas and dust emissions is conducive to environmental protection and is fully in line with the general trend of low-carbon economy.
