Yes. A custom plastic mold order can begin with just one mold set, so buyers do not necessarily need to commit to a large tooling quantity. The final quotation is determined by factors such as the part design, steel selection, cavity layout, mold life, finishing requirements, and production scope. Longterm lists a one-set MOQ for custom molds and also offers mold development together with injection molding for customers who need finished plastic parts.
A one-set minimum order makes low-volume tooling accessible, but the MOQ should not be confused with a fixed unit price. To receive a meaningful quotation, provide a 2D drawing, 3D model, or physical sample together with the preferred resin, cavity quantity, surface finish, expected mold lifespan, and required delivery scope. It is also important to state whether the order covers the mold only or includes molded parts.
For the referenced electronic-housing mold, the published product information identifies a precision tolerance of ±0.02 mm and a projected service life of 50,000 to 800,000 shots. These figures describe the listed product range and should not be treated as universal values for every mold design. Mold trials, dimensional verification, and a complete inspection before shipment are included among the stated quality-control procedures.
Delivery time varies according to the mold structure, tooling requirements, and selected service. The product listing indicates a lead time of 20–35 days. Longterm’s custom-mold service lists 25–35 working days, while simple molds under its mold-making and injection-molding service are listed at 20–25 working days. Buyers should confirm the applicable schedule during the quotation stage.
When molded parts are required after tool approval, the production plan can be arranged separately. The listed mold-development and mass-production service allows the production MOQ to be negotiated, with molded-part production scheduled for approximately 7–15 days after sample approval.
Longterm describes completed projects such as an electronic housing mold for a handheld device and a double-shot overmolding tool for a consumer-electronics shell. The company also reports ISO 9001:2015 certification covering the design, manufacture, and sale of precision molds, as well as the sale of plastic products.

| Service option | Minimum order | Published timing | Key consideration |
|---|---|---|---|
| Custom plastic injection mold | 1 set | 20–35 days for the listed product | Includes mold trial, dimensional inspection, and final pre-shipment checking |
| Mold making with injection molding | 1 mold set | 20–25 working days for a simple mold | Mass-production MOQ can be negotiated |
| Mold development with mass production | 1 mold set; production MOQ negotiable | 25–35 days for tooling; 7–15 days for production after sample approval | Useful when the buyer needs both tooling and finished components |
Yes. The stated minimum order quantity for the custom plastic injection mold service is one set.
Not necessarily. The available information does not provide a specific price or unit-price comparison. The quotation should be based on the part geometry, tooling materials, cavity arrangement, quality requirements, and whether production parts are included.
Yes. Longterm supports mold development followed by plastic injection mass production. The production MOQ is negotiable, and the listed manufacturing schedule is 7–15 days after sample approval.
Buyers seeking a smaller plastic mold order can start with one set rather than meeting a high-volume tooling minimum. To determine whether the project offers acceptable overall economics, submit the part design and production requirements and ask for a quotation that clearly separates mold costs from injection-production costs. Longterm Manufacturing Solutions Limited reports a monthly capacity of 15–20 injection molds and serves customers in North America, Europe, and Australia.
