How to solve the problem of obvious parting line (misalignment of parting surface)?
How does the parting line come into being? The injection mould is composed of two half-edge moulds. To get the product out of the moulds after injection, it is necessary to separate the two half-edge moulds. Where the mould is separated, there will be a line on the surface of the injection product, called the closing line.
Why do the products produced by the die have obvious parting lines?
The following reasons are indispensable:
1. Mould's own precision is not enough in machining (such as shape and position tolerance, module plastic deformation, etc.) resulting in the closing line setback.
2. Installation of precise positioning on parting surface is not enough, which can not play the unqualified parting line caused by precise positioning of cavity when clamping.
3. Fine positioning and installation, unreasonable selection and matching may also produce unqualified parting lines.
How to solve the problem of unqualified parting line?
1. Die design and the stability of its own action should be reliable.2. The machine-making process of the die is made with rigorous and reasonable material selection.
3. The precision of the die itself should be high. And its own accuracy comes from the accuracy of machine-added equipment and the accuracy of selecting spare parts.
Whether the product closing line is obvious or not is an important criterion for judging the quality of the die.
In more than ten years of customer cooperation programs, Yijing has helped many customers to solve such problems:
Zhongshan Fuhang Mould Manufacturing Co., Ltd. used before the precise positioning of the die because of the use of ordinary carbon steel, in the case of frequent opening and closing of the die wear faster.
Its customers complain that the product closing line made by the die after using for a period of time is obvious, which seriously affects the beauty of the product, and the precise positioning has to be changed every three months. It wastes a lot of maintenance costs and production time. Fuhang has also been worried about the loss of customers because of complaints from customers.
Finally, in 2014, Fuhang and Jingjie worked together.
Through cooperation and assistance, we recommend several precision positioning for Fuhang to use and run in. Matching material improvement, strict heat treatment process and first-class quality. Successfully solved the problem that the precision positioning of Fuhang die is not durable and the clamping line is obvious. Fuhang and a fine cooperation to help customers save manpower and material resources, successfully won the trust of customers.
