Mold Making Process

1. Requirements Meeting
A meeting is held to thoroughly discuss mold production requirements and address related technical issues, including material selection, structural functionality, product appearance, application environment, and inspection standards. This ensures clear project goals and smooth communication.

2. Mold Design and Flow Analysis
We use advanced simulation software to predict the flow behavior of molten material within the mold cavity. This analysis helps optimize mold design parameters to achieve the goals of high quality, low cost, and short lead time.

3. CNC Machining
According to the design drawings and production schedule, we use high-precision CNC equipment to efficiently machine mold components, ensuring dimensional accuracy and structural stability.

4. Sample Making (T1 Sample)
The first T1 sample is produced to verify whether the customized part meets the design specifications in terms of dimensions, functionality, and appearance. This is a critical step in the mold development process.

5. Inspection and Feedback
We conduct a comprehensive inspection of the sample’s shape, dimensions, color, and surface quality. Results are reviewed together with the client, and the mold design is refined as needed based on customer feedback.

6. Finalization and Production
Once the sample is approved by the client, a small batch trial production is carried out to ensure mold stability and product consistency. Full-scale injection molding production then begins.

7. Delivery
We ensure the mold is properly protected during packaging to maintain its appearance and structural integrity. Molds are carefully stacked on pallets, and shipment is arranged only after final client approval, guaranteeing safe and timely delivery.

One-stop Mold Manufacturing Service

Our “one-stop mold manufacturing service” covers a full range of services, including product design analysis, mold flow analysis, precision machining, assembly and debugging, and after-sales support. We also offer support and acceptance for existing molds, mold repairs, as well as comprehensive mold management and custom parts molding solutions. Regardless of the type of new mold you need, the BOS team always provides high-quality mold and custom parts molding services with its professional skills and exquisite craftsmanship.

Custom Mold and Tooling Materials

The selection of precision mold materials should take into account factors such as the product material (e.g., plastic, metal), production volume (batch/large-scale production), accuracy requirements (e.g., mirror finish), and operating conditions (high temperature/corrosive environments). Choosing the right mold material can not only enhance the mold’s performance and lifespan but also effectively reduce the cost of custom molded parts. So, what material should your mold be made of? BOS offers a variety of custom mold materials, and our experienced team will provide professional material recommendations based on your project requirements and product development stage. Below are some of the common material types we offer.

 Why Do We Recommend Test Molding?

Untested molds may lead to issues such as energy wastage during mass production (e.g., poor cooling system design causing equipment to operate under high load for extended periods) and manual rework (e.g., burrs on products requiring manual polishing). These hidden costs can accumulate and account for 15%-20% of production costs. The recommendation for mold testing is primarily to identify risks and ensure quality before mass production, achieving higher production reliability at a lower cost. Mold testing is like a “check-up” before mass production, spending a small amount to identify potential problems and ensure quality.

Moving Existing Tooling

If you have existing molds used for product production but are dissatisfied with your current supplier, BOS can provide a solution. We have successfully helped several clients quickly transfer their existing molds to us, minimizing the impact on the client’s part supply and subsequent production cycle. With manufacturing facilities in Jiangsu, China, we can produce your products in an efficient and cost-effective manner, helping you save costs. Additionally, we conduct thorough inspections of incoming molds before production to identify any issues that may affect quality or operator safety. At BOS, we take great care of your molds, both during production and storage. This attention to detail ensures that your molds will consistently produce high-quality, within-tolerance parts for an extended period, without the need for rework.
