A few days ago, a listed company visited and their aluminum die-casting molds were made of certain Shun 8407 and certain Bai 8407 mold steels. After die-casting 3000-4000 times, there were obvious cracks on the straight edges, and the products had many burrs and pits. They tried many ways, but couldn’t improve it. They asked how many products could be die-casting with my mold steel.
Objectively speaking, this is an unanswerable question. The same type of mold steel is used for different working conditions, and the number of mold lifetimes varies.
Mr. Chen, who specializes in die-casting aluminum shells for power tools, previously praised LG Mold Steel, saying, “LG’s materials are good, and the 13000 molds have not been eroded; In the past, H13 was made with 4000 molds and the hand molds were stripped of fur, but the molds had already cracked. According to Mr. Chen’s reply, LG has increased the lifespan of aluminum die-casting molds by three times without cracking.
Today, you came to tell me about another set of electric tool aluminum parts. When H13 was used for the feeding port, it was die cast 4000 times and had already been eroded and roughened. Now, LG mold steel is used, and 20000 molds still do not crack.
Although the data is not very large, the lifespan of the mold has increased from 4000 to 20000, which is a fivefold increase.
The working conditions that H13 cannot solve are generally extremely harsh. In extremely harsh working conditions, the service life is extended by 5 times, which is commendable and also the most testing of the performance and quality of mold steel.
Moreover, increasing the lifespan by 5 times means saving 5 mold repairs and 5 shutdowns.
Aluminum die-casting molds are relatively precise, and repairing the mold once costs 1000 yuan. If the mold is repaired 5 times less, it means saving 5000 yuan.
Don’t underestimate the value of this 5000 yuan. The current mold prices are so poor that even making a set of die-casting molds may not earn 5000 yuan. If a set of molds is repaired 5 times and you earn money, all of them have been repaired.
The die-casting mold needs to be repaired once when it is removed from the machine, and it also needs to be debugged when it is removed from the machine. It takes about 1 hour to complete the process, and reducing downtime by 5 times means you have an additional 5 hours of production time. The output value of this half day has already been worth a lot of money. At the same time, it also means that the boss paid half a day’s salary less.
Although mold steel is not valuable, high-performance mold steel can improve your production efficiency, reduce your mold repair frequency, lower your mold repair costs, and improve your productivity.
Mold steel with good performance is actually not expensive. It helps you achieve high efficiency, long lifespan, and low-cost use.
