Mold spring includes: the Japanese standard mold springs, German standard mold spring, MQB-type nitrogen spring, MQJ nitrogen spring, the MQC-type nitrogen spring, MQH nitrogen spring, polyurethane spring and usually the mould spring is the rectangular mold spring.
Second, material selection of mold springs
The mould spring material is generally used in the chromium alloy steel. The chromium alloy spring steel owns the characteristics of high temperature, rigidity and long life.
Third, the characteristics of mold spring
Rectangular mold spring is equipped with the features of small size, good elasticity, rigidity, high precision, rectangular material and separations surface spray (plated) to distinguish between different weights.
Fourth, the application of mold spring
The special springs is widely used in the stamping die, metal die-casting mold, plastic mold and other elastic motion precision machinery and equipment, automotive and other fields.
Fifth, mold spring production standards
Standardized mold spring production standards: ISO9001: 2000, Japanese JIS, ISO10243, NAAMS (North American Automotive Metric Standards), according to the different standards of production spring Intraday standard spring, the American standard spring, ISO10243 German standard mold spring.
Sixth, mold springs classification
The mold spring is divided into three categories: 1. metal spiral mold spring, a metal mold imported alloy spring steel spring, with reference to the ISO-10243 (the international standard) with metal spiral spring Industry Association of Japan (JIS) produce mold spring into two categories, quality and the United States DANLY (IEM) die springs and Japan Daido spring there is no difference, but the price of its approximately 40% lower. Widely used in molds, jigs, industrial clutch, brake components and various mechanical components.
1. the Japanese standard spring Classification: overweight load SB brown mold spring, heavy load the SH green mold spring load SM red mold spring, the SL blue mold spring for light loads, lighter load SF yellow mold spring. International Standard Classification: SJL green mold spring, SJM blue mold spring, SJH red die springs, SJB yellow mold spring.
2. Nitrogen spring
Mason the nitrogen spring domestic manufacturing quality has reached international standards, the price is about 50% lower, nitrogen gas springs interchangeable with the Dadco, Kaller, Misumi, Hyson, Bo top, Quiri brand nitrogen spring, short delivery and quick service. And the categories of Mason nitrogen spring: MQB-ISO international standard, MQJ-structure compact, MQC-super-compact, MQH-special thin structure type.
3. Polyurethane spring
Polyurethane spring classification: EX high load polyurethane spring, A-type high-load polyurethane spring, the LA high load polyurethane spring, the UT high load polyurethane spring the UD type high load polyurethane spring and so on.
