Plastic Injection Molding
Plastic injection molding is a technique that transforms molten thermoplastic into solid parts by forcing it into molds. This process enables efficient and large-scale production while maintaining consistent quality in every molded piece.
Overmolding
Overmolding is an artful combination of different plastic materials, seamlessly molding one over another. This process enhances functionality, aesthetics, and grip, while simultaneously reducing assembly time and costs. Experience the synergy of materials in a single, efficient manufacturing step
Insert Molding
nsert molding is a technique that encases a pre-set insert with plastic, seamlessly merging metal and plastic components. This process enhances overall strength, simplifies assembly, and ensures precision integration, showcasing the power of seamless fusion in manufacturing.

Our Injection Molding Processes
See how we process your orders, from quotation to tooling, as our machines and efficient team ensure you receive your molds and parts within the scheduled lead time.
Design Submission
Kick off the process by uploading your 3D model files online, or you could email us directly. Seamlessly supports various file formats such as [.STP], [.STEP], or [.STL], ensuring compatibility and ease of use.
Instant Quote & DFM analysis
Upon submitting your project, an immediate quote will be provided. Our sophisticated algorithms conduct a thorough analysis of your design, pinpointing potential manufacturability issues and fine-tuning for optimal printing efficiency.
Order confirm & Deposit
Client confirm the price and order for us. Some deposit we use for formal DFM report, mold design and purchase the plastic injection mold steel material. We have very strictly process for injection mold project. We care about.
Project Kick off in MY Prototyping
Once we receive the client’s order confirmation, we organize interior team to study client’s part design, and emphasize the client’s request , remark the plastic part and plastic injection mold important points, the risk we need avoid and the back up solution. To make sure the plastic part quality.
DFM & Mold design confirmation
Before project kick off, we confirm the team member responsible for different position. After project kick off, the designer need supply the DFM report. We discuss with client and after the confirmation, we could submit the mold design, only the mold design confirmed by clients, we could start the next step.
Steel cut & mold manufacture
Client confirm the mold design, we start to cut the steel. It takes 2-3 working days to purchase, and we start the plastic injection mold manufacturing then, the same time, MY prototyping send the mold time schedule to clients. It usually takes 20-45days to get the T1 samples, depends on the mold size and mold structure.
T1 sample and mold maintenance
Clients could clear about we need to do at each step from the mold time schedule. After first mold try out, we would send T1 samples to client for confirmation, and MY prototyping supply the mold maintain solution. After 2-3 times maintenance, we’ll get the final good assembly plastic parts, during this step, we help clients deal with the surface finishing.
Final sample confirmation
We ship the final samples to clients, clients need confirm the final samples including the surface treatment to MY prototyping. If client have the special request of the packaging, need tell us and confirm also. We start the plastic part production according to client’s quantity.
Part production &QC & delivery
At MY prototyping, we package and QC the part for first time, during plastic part production.Once products manufacturing finish, we ship the parts to warehouse, we arrange the QC team for second time checking. We’ll arrange the the part delivery according to our delivery term. And we could freely supply client prepare everything if client has their own forwarder to ship.
