In China, many seemingly simple, commonly used and cheap plastic products have not only low technology content but also large market.
Take the small plastic water valve with a price of only 0.8 yuan as an example. It's not too exaggerated to make 10000 yuan a day. Many manufacturers still take the previous idea to do business, do the same products with lower prices, and expect more monopoly market. In fact, with the development of the market, this idea has completely failed.
Mr. Meng's plastic water valve has achieved a small monopoly in the industry, and many people are curious about how he made it. The highest price of this kind of valve in the wholesale market is no more than 0.8 yuan, but this small product brings Mr. Meng 10000 yuan profits a day.
For this product, the most difficult part is the connection part between the valve core and the valve body. Because it must pass the "water pressure" and "water hammer" test, the sealing requirement of the product is very high. But those who are involved in water supply plastic parts all know that the most troublesome point of this product is the core pulling and placing O-type seals. Generally, the qualification rate of this product depends on the skill level of the technician. If the technician's level is high enough, the injection molding machine and mold control will be good enough, and the production can be stable, then the profit of the product is very considerable. But if the technician is in a bad mood today and fails a little, it will be troublesome. The product yield is very low, and it is difficult to find the problem through the naked eye, which can only be found through the later inspection, thus it increases a lot of testing costs.
At the starting of investing into this project, Mr. Meng strengthened his determination to do automation. If he could not achieve automation, he would have to rely on the technician to do it, which means it would be hard for him to make money. In order to realize the automation of this project, the following key points should be adopted:
1. The repeated positioning accuracy of the product is within 0.1 mm
The repeated positioning accuracy of traditional injection molding machine is about 0.15-0.2mm. As Mr. Meng wants to realize the automation of placing seals, the positioning accuracy of the template must be within 0.1 mm. Otherwise, the O-ring will be hardly placed in the right position, which is easy to cause water leakage or direct damage.
2. The injection repeated positioning accuracy must be high
It’s hard to inspect the product through the visual inspection. Thus it’s important to ensure that quantity of material of each injection process are the same and the injection speed and the screw stroke are consistent, so as to ensure the qualification rate of the product as far as possible without passing the extra inspection.
In accordance with the above requirements, we recommend the "TLE fast machine" series servo injection molding machine to Mr. Meng, which can effectively realize fully automated production and reduce the daily cost by about 30% compared with the peers. Thus Mr. Meng quickly occupied more market space.
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.
