We offer a custom-made machine that is the only one in the world, as we are the only one specialized machine manufacturer of the hot coiling machine in Japan.
Coil Spring Manufacturing Equipment
Our coil spring manufacturing machines can produce various types of coil springs.
These coil springs are used for automobiles, trains and heavy machines.
We have made the machines for wire diameter up to 100mm.
Taper Rolling Machine
This machine performs to roll a heated end of raw material, which shapes coil spring into tapered form.
The method of coiling can be divided into 2 types. One way is forming into coiling shape by coiling pin.
Another way is forming into coiling shape by mandrel and moving guide roller.
Coiling process is important to determine the quality of coil spring as its diameter, free height, load, spring rate, etc.
End of coil spring is formed as pigtail shape. Our machine performs to forming pigtail shape automatically with forming jig that moves by pre-set program. Change of forming jig is necessary according to shape of pigtail.
Quenching / Tempering, Shot-peening
The purpose setting process is to improve fatigue strength of coil springs, and enhance its elastic limit. Setting process can identify "specified load" or "specified height" of coil springs.
Load Testing machine
This machine can measure the load of coil springs with its specified height. Then the coil springs will be classified by the results of its load.
Leaf Spring Manufacturing Equipment
Since the day of establishment in 1910, Morita & Company has greatly developed with growth of Automobile industry. Our achievement and its originality has been approved as a leading brand for spring manufacturing machines, and M&C brand has gained high trusts internationally.
Material Cutting and Punching machine
Material Cutting machine
The machine performs to shear a material of leaf spring to the required length.
Taper Rolling machine
The material of leaf spring can be tapered thinly by pressure of taper roll.
End Forming machine
This machine performs various forming for material end.
Eye Forming unit
This machine automatically forms heated end of leaf springs into eye shape.
Camber Forming and Quenching.
NC Camber unit
This equipment makes a whole heated leaf spring into camber form by using universal die (Jack type). The formed leaf will be transferred into quenching tank.
Tempering, Shot-peening, Leaf painting, Assembly, Setting
Setting and Load Testing machine
This machine can measure load of leaf springs with its specified height. Then the leaf springs will be classified by the results of its load.
Fatigue Testing machine
This machine is generally used at a research and develop department in our customer. It can test the fatigue of leaf springs.
