Key Word: Taili Plastic Machinery; Taili Plastic Machinery-Capacity Improving Expert; Efficient; Stable; Sunken of Template’s Central Part
Mr. Wang is a veteran in the injected washbasin industry. He used to believe the injection molding machines of different brands are the same, regardless of the big brand and the small brand. After working for about two years, the center part of the template will be sunken. If kept working for another period of time, the template and the pull rod will break down. So there’s only one principle in his mind while choosing the machine- low price.
At Taili Plastic Machinery’s first visit in Mr. Wang's factory, Mr. Wang's attitude was very clear. Don't talk to him about quality or advantages. He has been working in this industry for nearly 10 years. He has come across many different troubles and problems and has tried a lot of different brands of machines. He said to us at last, “Let’s talk directly about the lowest price you can offer. If it’s acceptable, I’ll give you the order."
We were astonished that Mr. Wang said the central part of mold would be sunken after 2-year’s work of injection molding machine. This phenomenon was quite normal 10 years ago. But now such low-level mistake can’t happen about processing technology and material selection for most injection molding machines. We carefully checked the parameters and the situation Mr. Wang's injection molding machine and turned to be shocked at last.
In the plant, we found that the injection feedback pressure of the injection molding machine was 170-180bar, and the clamping force of the template was above 160 bar. When the injection molding machine was storing materials, the machine let out sad sound as it seemed to have predicted its tragic end. In my impression, this kind of injection molding parameter design could be called suicide-type parameter design. This was what caused the short service life of Mr Wang’s machine. Taili Plastic machinery has been emphasizing with customers that low mold locking pressure and low injection pressure are the essential features of good injection molding machine. Generally, for ordinary products, the injection pressure is generally required to be lower than 120bar and the mold locking pressure shall not exceed 120 bar.
We asked Mr. Wang's adjusting technician how he set the parameters. He said that the thinnest part of the product wall thickness is only 0.75mm, and the mold was prone to eccentricity after a while of working. If the injection pressure and locking pressure were not set high, the product will be defective. On the basis of high injection pressure and mold locking pressure, melting temperature should be improved and the machine could barely keep working.
For this situation, we strongly recommend to Mr. Wang Taili Plastic Machinery’s TLE series fast injection molding machine. With the newly-developed design of oil circuit and pressure control, the injection rate can be increased by more than 30%, and the cycle can be controlled at about 10 seconds. On the basis of not changing the original mold, the injection pressure and injection speed required were greatly reduced and further improved the durability of the machine.
One year later, every time we visit Mr. Wang, Mr. Wang is always very happy. He really didn't expect that the new technology really helped him solve the sunken problem of template. The extension of the machine life has greatly increased the profit margin of his products.
Taili Plastic Machinery always keeps in mind that what a good injection molding machine factory should do is to help improving the capacity and boosting the profits, rather than offer the similar products the customers need. This is also what Taili Plastic Machinery keeps doing.
