Many friends have complained to me that profits you can make in the injection molding industry are low. Peers compete fiercely and the price has to be turned lower and lower. Thus, fewer profits can be made.
I would like to say that every product is worth digging into deeply, and only have you tried you can make it. Every simple can be profitable.
Today’s story is about Mr. Lu from Yiwu. His main business is doing OEM production and he has been producing OEM for big brands all year round. He has been complained about his business a lot. He had to make every effort to meet customers’ needs and the money usually was not given timely.
He got a major Japanese brand's processing business last year, making ultra-quiet electrical fans. The running noise of the general fan is about 45 decibels, but the noise of this ultra-quiet fan is generally about 25 decibels. This big brand has already found several processing factories who said that they could get the work done. However, the demands couldn’t be met. Mr. Lu thought that the work could be done with a Japanese injection molding machine. But the price of Japan's precision injection molding machine is very high. The interests will be decreased to a great extent if he buys the new machine.
Mr. Lu came to ask Taili Plastic Machinery what should be done to achieve ultra-quiet in accordance with the requirements of the Japanese brand. To achieve ultra-quiet, on the one hand, it is related to the internal bearing selection; on the other hand, it’s about the dynamic balance of plastic parts. The good dynamic balance of the plastic fan blade means that the fan shakes little when it rotates. If the dynamic balance cannot be well controlled, the bearing will not play its role no matter how good it is.
As for how to improve the dynamic balance of fan blades, Taili Plastic Machinery suggests to Mr. Lu that he should do from the following aspects:
Injection molding machine’s repetitive positioning accuracy
The repetitive positioning accuracy must be as high as possible during the injection of the injection molding machine, which will ensure that the weight of the product will not fluctuate. Thus the dynamic balance accuracy of the product under the same assembly accuracy will be ensured. The repetitive positioning accuracy is generally closely related to the structure of the mechanical parts of the injection molding machine. The simplest test method is to observe whether the opening and closing time of the injection molding machine is controlled within 3s, and the jitter of the injection molding machine has high repetitive positioning accuracy.
Injection molding machine’s injection response speed
To ensure that the weight of the three fan blades is consistent, the injection response speed of the injection molding machine must be increased. The TLE series servo injection molding machine can effectively ensure the change of injection response speed during the filling process from the mold nozzle to the cavity.
Injection process
In the injection process, select one-time molding as much as possible. The product should not be kept under pressure. Because the flow of raw materials in the various shunts is different during the pressure-keeping process. Then the dynamic balance of the product will be damaged.
Mr Lu saw that I was right, and requested that the mold be placed on my injection molding machine for trial molding. After a few molds, the product was taken to the brand side for inspection. As expected, it was easily passed once.
According to Taili Plastic Machinery’s advice, Mr. Lu has achieved the demands of the Japanese Brand and has never worried about the interest margin. He is now leading in doing the ultra-quiet electrical fan.
Taili Plastic Machinery has been helping customers to solve the problems and improve profit margins. It is the rule we always remember: selling machines is only the beginning of cooperation.
