Customized Plastic Injection Mold notice
- Demand customization
Our company can customize the mold opening according to the drawings or samples you provide. You can modify and design the structure according to your requirements, model the overall three-dimensional rendering for you, and perform mold opening quotation and product quotation according to the three-dimensional, which is convenient You account for the overall cost of your product. - Proofing
After preliminary determination of the details such as style, size, material, price, etc., as required by the customer, we can provide prototype samples in advance before opening the mold (Note: The company will charge an amount of proofing fee according to the actual situation. Usually 3D printing or NC Milling), so that customers have a more intuitive understanding of product details. - Purchase contract
If there is no objection, both parties can sign a purchase contract (our company has a contract style), and the contract will detail the product information, delivery time, acceptance standards, settlement methods and other details. No refunds or refunds will be accepted for production. - Customization period
During the mold opening, we will give you a picture of the progress of the mold every 3-5 days. If the customer needs to change the shape of the product during the mold opening period, we will not charge any fee for the product before the processing. If the mold at the changed structure has been processed , We will evaluate and charge additional fees as appropriate. Review the product assembly and other details after the prototype is sampled. If there is any customer dissatisfaction, we will modify it until the customer is satisfied with the product, and finally confirm the product is OK. Later molds are injection molded in our company, and repair and maintenance of the molds are free. - Cargo packaging
Under normal circumstances, guests do not have special packaging requirements, our company uses ordinary carton or paper bag safe packaging (this packaging is free), if it is anti-collision goods, our company can carry out fine packaging according to the packaging method requested by the customer, but the resulting costs It will be borne by the guests themselves. - Cargo transportation

Injection Plastic Products Mold process description
| Numbering | Specific matters | Detailed description |
| 1 | Selection of mold steel | mold steel: 45#, 50#, P20, H13, 718, 2738, NAK 80, S136, SKD61, etc. This type of product is a type with high appearance requirements, and the surface of the product requires high brightness, so the choice of mold material is very important, but considering the price, generally choose P20 steel, P20 is pre-hardened steel, not suitable for heat treatment , But can be nitrided, hardness 280HRC~400, because it has been pre-hardened, mechanical cutting is not difficult, and the hardness of this steel is higher than that of medium carbon steel, the deformation is also more stable than medium carbon steel, so in plastic mold It is widely adopted. |
| 2 | Formwork | LKM, HASCO, etc. |
| 3 | Design software | UG, PROE, CAD, CAXA, etc. |
| 4 | Plastic material | PP, PC, PS, PE, PU, PVC, ABS, PMMA, etc. |
| 5 | Design of mold structure | A professional designer designs a reasonable structure for you to achieve the shortest production cycle and reduce the follow-up processing procedures to improve production efficiency. Cold runner, hot runner and hot nozzle cold runner structures are the three most commonly used. |
| 6 | Cooling water system and gate design | According to the product’s structural characteristics and product appearance requirements to design a reasonable gate form, there are Large gate, latent gate and fan gate, needle valve type, etc., reasonable cooling system The mold temperature can be balanced in the shortest time to improve the accuracy and accuracy of the product Product production efficiency. |
| 7 | Parts configuration | Inserts, guide columns, guide sleeves, sliders, slider sleeves, inclined top blocks, etc. adopt wear-resistant standards Parts to increase the service life of the mold. |
| 8 | Cavity | Single/Double/Multiple |
| 9 | Mold surface treatment | Industrial polishing grade |
| 10 | Product mold time | 6-90 seconds |
| 11 | Target mold life | 500,000 times or more |
| 12 | Time required to complete the mold | 25-70 days |

OEM Tooling and Production FAQ
Which files support a quotation?
STEP, STP, IGS or X_T files are useful for geometry review. In addition, a 2D drawing can define tolerances, materials, finishes and inspection points.
What happens before mold construction?
First, our team reviews manufacturability and commercial requirements. Next, both parties confirm the tooling plan, material, schedule and approval process.
Can one supplier support tooling and molding?
Yes. Leiyuan can coordinate mold development, sampling and injection production according to the agreed project scope.
For related capabilities, review our custom injection molding services and plastic extrusion manufacturing. For broader product-development context, the NIST Manufacturing Extension Partnership product design and development overview discusses prototyping, material selection, testing and the path from concept to manufacturing.
Commercial note: final mold cost, lead time, cycle time and tool life depend on part geometry, steel, cavities, resin, tolerances, finish, validation and production requirements. Confirm these points in the approved quotation and tooling specification.
