Product Description
We are one of the most famous JIS and ISO die springs brand suppliers in Japan, European, and America.
Our springs mainly produce Japanese standard springs(JIS springs) and European standard springs(ISO springs). The raw materials mainly use 55CrSi and 50CrFn because of their good quality. These two materials can ensure the high quality and durability of our springs. Our durability can guarantee more than 300,000 punching times, and if the cost is increased, the durability can reach 1 million times. High durability makes our products very advantageous in price and cost performance.
The sand removal effect of our springs is excellent. General factories generally do not remove sand, or generally, remove sand mechanically in order to save costs. We use relatively primitive manual sand removal to ensure that each spring is of high quality
We use unique electrostatic painting technology, which is environmentally friendly. Only environmental protection can ensure the sustainable development of resources.
Our springs have more advantages in terms of durability because we are very careful about the standing treatment. Others generally only do one set-up treatment. In the contrast, we do four set-up treatments for each spring. We will do more than 6 set-up treatments if there is a higher requirement for durability.
JIS and ISO die springs are often used in industrial production. JIS and ISO die springs can be used in stamping molds, plastic molds, die-casting molds, automobile molds, and also in automation equipment, elevators, machine tools, construction machinery, environmental filter presses, motor switches, valves, and many other fields.
