ACO Mold is a Chinese injection molding company, concentrating on mold making and injection molding for more than 10 years. Besides, we also provide services such as painting, skill print, ultrasonic welding, assembly, retail packing etc. We have our own fully equipped injection molding factory in Shenzhen China, so we are fully capable of providing one-stop plastic processing service. Last year, we made a set of injection mold for plastic molding in-house for a US company. The material of injection molded parts was required to be special ABS.

Before mold manufacturing, ACO Mold did DFM for manufacturability and product analysis. We confirmed important information and product details with customer, such as parting line, gate position, ejection etc.

DFM was approved by customer, we started mold design immediately. ACO Mold performed mold design based on the details confirmed with customer.

Due to there were changes on features, so we need to remake the EDM copper. Holes position were all moved and shaped were all changed, that’s why we need rework hoes, and we need new EDM copper. The difference between old version and new version in plastic part design as below pictures:

Injection mold manufacturing including sampling took 4 weeks. We regularly reported mold making progress via sending mold processing and mold fitting pictures or video. After injection mold making was done, we did T1 sampling.
After receiving customer’s comments about T1 samples, ACO Mold did mold modifications based on updated part design.

Changes as below:
1) Angle changed from 45° to 20°

2) Thickness increased clip to hold board

3) Thickness increased clip to close enclusure

T2 samples were shipped to customer for verifying. Customer was satisfied with them, and the injection molding in batch is approved.
