Rectangular springs are round in shape and flat at both ends. They are made of steel with rectangular cross-sections. They are called rectangular springs. There are 4 commonly used colors.
We must pay attention to these precautions when using this spring. Under normal circumstances, green springs are generally preferred. When the elasticity is large, brown springs are considered. When a large shrinkage rate is required, consider using red.
The spring cannot exceed its root limit compression, that is, when the mold is closed, there must be a gap between one circle and the other adjacent circle, otherwise the mold will not be in place.
When the mold is large, the space is large, and the stripping force is large, use a large spring as much as possible, otherwise use a small spring. Commonly used are diameters of 20, 25, 30, 35, and 40mm, and the length must use the standard length.
The other type uses a nitrogen gas spring, the outer shell is a steel body, and the inside is filled with nitrogen gas. It is widely used in industrial mold manufacturing. As a new type of elastic component, it has small size, large elasticity, long stroke, stable work, and precise manufacturing. It does not need to be preloaded like a spring, and the elastic curve is quite stable. There is also a compression spring, which is also commonly used, and is also distinguished according to color. Generally, compression springs include plastic compression springs, stainless steel compression springs, and industrial compression springs.
