Today, while going down to the workshop to pick up products, I saw injection molding workers complaining that a set of OEM molds always produce products with sharp edges, which leads to an increase in the amount of processing work in the later stage of the product and greatly affects production efficiency. I believe many friends know what Pi Feng is! Many staff members dislike products with more edges because there are more processes to be processed in the later stage. They prefer products without edges or with fewer edges because they can be processed and placed in the finished product area, making their work easier!

There are four places where injection molds are most likely to have sharp edges

1. The parting surface has a sharp edge

Improper flying, misalignment, excessive injection pressure and molding, and loose mold adjustment can all lead to sharp edges.

2. Top pin with sharp edge

In mold production, frequent movement of the ejector pin can easily wear and enlarge the ejector pin hole, resulting in gaps.

3. Place oneself in a prominent position

Each row has a matching shovel level that moves as frequently as the top pin, and is also the most worn part. If the shovel level is not worn enough, the product will become sharp.

4. Piercing and piercing with a sharp edge

Mold steel is prone to lodging and deformation without hardening.

Only by strictly controlling the quality issues in these four areas during mold design and manufacturing, can we effectively control the appearance of the product in the later stage of production.

That's all for today's sharing. If you have anything else to add, feel free to contact me anytime!
