Import Die Mould Spring — Buy in Bulk from Supplier in China

The Die Mould Spring offered by Spring Die Mould Part Co., Ltd. is an industrial‑grade spring designed for moulding and casting equipment. It conforms to ISO 10243 and JIS B5012, ensuring dimensional stability and load performance required in precision tooling. The product is supplied with an outside diameter that can be selected anywhere between 10 mm and 100 mm, allowing adaptation to a broad spectrum of machine designs. Each spring is engineered to distribute load evenly across the mould cavity, reducing wear during repeated cycles.

Spring Die Mould Part Co., Ltd. typically manufactures the springs from heat‑treated carbon steel, a material standard for durability in high‑stress environments. The usual hardness falls within 45  -  55 HRC, providing a balance between elasticity and strength. Industry practice sets the diameter tolerance at ±0.2 mm, which the supplier respects in its machining process. Such specifications match the typical requirements for automotive, aerospace and heavy‑machinery mould applications.

The springs find frequent use in automotive component casting, aerospace part moulding and heavy‑machinery production lines, where consistent performance is critical. Buyers can order quantities that suit their project size, with the supplier stating that the minimum order is flexible rather than fixed. Trade terms include FOB or CIF shipping, and payment can be arranged through L/C or T/T according to the buyer’s preference.
