Materials for Injection Molding

These are commonly molded plastics that our injection molding service provides. After knowing the basics of materials, like common grades, brands, advantages, and disadvantages, choose the right injection molding material depending on your application requirements.

Tooling Materials

Before injection molding process starts low or high-volume production, a high tolerance CNC machined tooling is needed. Most commonly used materials include:

Tool Steel: P20, H13, S7, NAK80, S136, S136H, 718, 718H,  738 Stainless Steel: 420, NAK80, S136, 316L, 316, 301, 303, 304

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.

FAQs about Injection Molding Service

Our mold-making process includes 6 steps:
Step 1: Production arrangement: Determine all of the requirements and arrange the production.
Step 2: DFM report analysis: Provide free but detailed production DFM report for further feasibility analysis.
Step 3: Production the mold: Put the mold into production and provide the Tooling Schedule form for the whole cycle for clients to check the process at any time.
Step 4: Free sample to test: Put the mold into production and provide the Tooling Schedule form for the whole cycle for clients to check the process at any time.
Step 5: Mass production:Client confirms the samples are qualified, then officially proceed with the subsequent production.
Step 6: Mold saving: Production is completed and delivered after quality inspection. Mold will be cleaned and properly stored for the next round of parts production.
Tolerances are crucial in injection molding; without proper specification and control, assembly issues can arise. At MY Prototyping, we adhere to the ISO 2068-c standard for molding tolerances, but can accommodate tighter specifications if needed.
We have no minimum order requirement. However, larger quantities will yield more competitive pricing.
Once an order is placed, mold design and creation typically take around 35 days, with an additional 3-5 days for the production of the molded parts.
The cost of our services varies based on several factors such as component size, mold complexity, number of cavities, material type, and post-processing requirements. We provide quotes after analyzing these factors on our platform.
