Brief Introduction of Mould Spring

Mould Spring

Mould spring includes JIS mould spring, DIN mould spring, MQB nitrogen spring, MQJ nitrogen spring, MQC nitrogen spring, MQH nitrogen spring, polyurethane spring, etc. In general, mould spring refers to rectangular mould spring.

Mould spring is widely applied for punching die, metal die-casting die, plastic die and other elastic motion precision machinery equipments and automobile area.

Material of mould spring is usually chromium alloy steel. Chromium alloy steel resists heat with large rigidity and long life span.
Rectangular mould spring is characterized by small size, sound elasticity, large rigidity, high degree of precision, rectangular making materials, surface spraying with different colors to differ loading from each other, and beautiful appearance.

At present, production standards of standardizing mould spring are ISO9001:2000, JIS, ISO10243, NAAMS. Mould springs produced according to different standards are JIS mould spring, American standard mould spring, and ISO10243 DIN mould spring.

Metal Spiral Mould Spring

Metal spiral mould spring is widely used to mould, fixture, industrial clutch, brake construction element and various types of mechanical component.

JIS spring can be divided into overweight load DB dark brown mould spring, heavy load DH green mould spring, medium load DM red mould spring, light load DL blue mould spring, lighter load DF yellow mould spring, etc.

International standard mould springs are classified to SJL green mould spring, SJM blue mould spring, SJH red mould spring, SJB yellow mould spring, etc.

Polyurethane Spring

Polyurethane spring consists of EX-type high capacity PU spring, A-type high capacity PU spring, LA-type high capacity PU spring, UT-type high capacity PU spring, UD-type high capacity PU spring, etc.

Application Status
Nowadays, circular section or deformed section (square, rectangle, flat shape, S-shaped, D-shaped) wire cylinder screw compressor spring, rubber (neoprene rubber, PU rubber) spring, nitrogen spring and Belleville spring are applied in different types of moulds. However, analyze from applied range and quantity, circular section wire cylinder screw compressor spring are not applied as much as before, while deformed section wire cylinder screw compressor spring, especially S-shaped and D-shaped wire cylinder screw compressor springs are used more frequently. Rubber spring especially PU rubber spring keeps on a stable place. Belleville spring and nitrogen spring are still being tried. If seems there is a new market for them, but as to the static and dynamic characteristics, whether they are suitable to use has not been known.
