Plastic Injection Mold Making for USB Enclosure

Basic part information:

· Part size: 46*30*43mm

· Material: ABS

· Color: Black

· Surface finish: inside polished, outside structur VDI 3400-33.

Basic mold information:

· Gate type: sub-marine at ejector pin

· Cavity number:4

· Material: S136H

· Shrinkage: 1.005

We start every project with a comprehensive DFM (Design for Manufacturability) analysis to ensure the best results. This includes verifying key details such as parting lines, gate positions, and ejection methods to optimize the injection molding process.

After confirming the details of the drawings, we started making the moulds.

We experience the following problems in the process of making plastic mold parts:

Customer Feedback: There are ridges inside the USB C/A openings. That make problems if we built in the electronic parts. Please reduce it as much as possible.

The solutions we provide: For the ridges in openings, we will improve and avoid it.

Customer Feedback:  Please reduce the lines as much as possible while production. A painting is not a option.

The solutions we provide:  Next trial , we will set The oil temperature more than 110 degrees, the line will be very shallow, not completely removed.

Customer Feedback: The defect because the close pillar should be removed.Please change it as you recommended and send me the revised stp-file edition.The pillar can not be very thin because the stability.

The solutions we provide: The pillar of Core needs to be reduced plastic and the bone position needs to be removed.In addition, we want to add 0.1-0.15MM to the single side of the biggest point of the product and make the slope a little bigger, so it is not easy to drag marks.

We changed the mold according to the above problems, and the test result was very successful, avoiding and improving the mentioned problems.

Customers are very satisfied with the product results, and gave us other similar project production, while we also have the ability to meet customer needs, to achieve a win-win situation.
