Is the salary of injection molding machine master high?

The adjustment salary of injection molding machine is about 5000- 10000. Looking at personal skills and actual debugging ability, the debugger should not only be able to debug the machine, but also know die Dekuma and go abroad to debug the mold engineer, so the greater the ability, the higher the salary.

Because of my work, I often have the opportunity to sit with the bosses of major plastic factories for tea and chat, share their views on the market and analyze the latest technologies and products.

Because of his rich experience in machine adjustment, he often acts as a "Depth Charge" and is active in the production line to help solve practical problems.

Yesterday, Mr. Lei from Ningbo called me. Tang Palace, I have a reluctant request. Can you come to my factory and have a look? I have a product that is badly adjusted. The employee I was in charge of asked me for a raise last year, but I didn't promise him. As a result, he left in a rage.

I didn't expect that the smooth mold I used to play has not been adjusted well.

When I went to Lei General Factory, I found that the original boxes were all made of cosmetics, and the main material was PMMA.

The biggest problem of the product is uneven gloss at the bottom, which is not obvious under ordinary light, but very obvious under side light, and the spots are very ugly.

Teacher Lei said that this mold was smooth before, and I adjusted it according to the previous process. It doesn't work now either.

Analyze the reasons

I don't care about the wage dispute between the boss and the employees. Let's consider the product.

In fact, this kind of transparent PMMA product, if a slightly experienced master knows: the injection speed should be slow and the injection pressure should be high, just push it slowly.

But in fact, a truly experienced master will tell you that this product requires higher hardware configuration of injection molding machines and molds, as well as higher requirements for material selection and drying process. In order to make the product 100% meet the customer's requirements, all variables must be limited.

On the contrary, the process of adjusting the machine is at the end, because if this product depends on parameters, the yield will be greatly reduced due to changes in temperature and processing environment, which will greatly affect the profit margin.

solve problems

Therefore, I first asked General Lei a few questions:

(1) Did the brand and drying time of materials change after the employee left the company? Generally, PMMA materials are required to be dried below 90 degrees for 2-4 hours, and the specific time depends on different brands of raw materials and air humidity.

(2) What number of injection molding machine was originally used for this mold? Have you tried it on the original injection molding machine? There is also some adaptability between the mold and the injection molding machine, especially for the mold with multiple cavities, the balance between multiple cavities is the most difficult to adjust, and the injection molding machine will generally optimize and compensate. )

(3) Carefully check whether there is any operation omission on the surface of the lower die.

I don't know the result, but I found that the entrance diameter of one cavity of the mold was obviously reduced. It is estimated that there was an untreated small head during the previous urgent operation, which led to the collapse of the mold.

There is no way but to readjust the mold entrance.

I always think that a good injection molding machine manufacturer should help customers improve their production capacity, profit margin and market share.
