1. Providing Samples or Images
Provide Huayi with 2D/3D design drawings or samples of the desired product, and discuss mold development with Huayi.

2. Plastic mold development discussion
Provide detailed product requirements to Huayi and let Huayi provide more appropriate solutions based on past experience. After the requirements are finalized, Huayi will provide a quotation.

[Reference Product Requirements Form]
A. Product demand (annual or monthly)
B. Application scope
C. Product appearance requirements
D. Inspection size standards
E. Functionality
F. Whether there are matching parts
G. Mold material
H. Product material
I. Budget range

3. Quotation and Order Confirmation
Confirm the order by placing an order based on Huayi's "Mold Quotation" and "Plastic Part Quotation." The subsequent process involves mold development and takes an average of 1-3 months depending on factors such as the size of the product mold, the number of cuts, and the mechanism design.

4. 3D Design Modeling
At this stage, the original 3D design is transformed into a plastic mold design, which is an important process that affects product quality. The following key factors are often considered：
A. Hooking: Hooks can affect the quality of the final product in the production stage. If there is an error in the design evaluation during the modeling stage, it may lead to demolding difficulties, or even cause the entire set of molds to be scrapped and unusable.
B. Demolding angle: Friction will occur during demolding. If the angle is insufficient, it will cause the mold to be unable to detach or create mold deviation when it does, resulting in side scratches on the parts. If the details are not precise enough, it can seriously affect the entire production cycle of the product.
C. Injection point selection: The injection point affects the surface and binding lines of the product. If it is not well-designed at the beginning, it will affect the smoothness of the entire production process of the product.
D. Cooling and hot runner: The cooling runner produces a runner. The longer the runner, the greater the shear heat, which will result in a lower filling effect of the final product. It also involves the need for simple runners, but the cost is relatively low; the hot runner (without runner) does not solidify the plastic in the runner after each injection, and the waste in the runner does not need to be removed during demolding, but the cost is relatively high.
E. Mold material: The mold material affects the mold lifespan. The better the material, the longer the lifespan, which can be determined based on the product material and quantity. Common mold core materials include: STAVAX, NAK55, NAK80, all of which can achieve a lifespan of more than 500,000 mold times.

5. 2D Drawing Separation
Convert the drawn 3D mold into a 2D processing drawing.

6. Production Scheduling
Schedule the dispatch date and expected completion date for the processed 2D drawing parts.

7. Machining
During the plastic mold development process, multiple machining machines are used, such as CNC milling machines, lathes, grinders, drills, etc., to perform mold seat machining and other processes.

8. Assembly and fitting
After the mold base and mold cavity are completed, they are assembled into male and female mold modules. Once assembly is complete, they are checked again. When the mold is closed, a red ink mark is made on the other side to indicate that the mold surfaces are properly aligned. If there is no ink mark, it means that the mold base has a tolerance issue that needs to be fixed, otherwise the product may have burrs after molding.

9. Mold trial (the first trial is called T1, the second is T2, and so on)
After the assembly is confirmed, the next stage is injection molding. Not all mold development factories have injection molding machines, and some factories outsource this process. However, Hwayee has been established for many years and provides a one-stop service internally. After the mold assembly is completed, the trial molding process can be carried out in-house, without outsourcing, saving transportation time and improving efficiency and quality.

10. Inspection and acceptance closure
According to the customer's requirements, the appearance, size, function, etc. are inspected and quality checked. Generally, in the trial molding stage, in order to ensure the actual size of the plastic product, the mold size is subtracted in advance, and then adjusted through precision calibration and correction before trial molding again.

After the above process is completed, Hwayee will attach a QC inspection table. If there are no issues, the project will be closed.

Clear communication in the early stages will result in a smoother production process. If it is the first time to develop plastic molds or the understanding of requirements is not clear enough, you can directly contact Hwayee. We have rich experience and professionalism and are always ready to help.
