Selecting a double shot molding process starts with the part itself: identify the materials or colors it requires, the precision needed between molded sections, and the production volume. Then compare the mold design, quality checks, lead time, and ongoing support with your project requirements.
Double shot overmolding is suitable for components that combine two materials or colors in a single molded structure. Listed material pairings include ABS+TPU and PP+TPE. Check that the proposed combination fits the part's functional and design needs; the available product details do not provide a broader compatibility list.
Next, review the part geometry and required alignment accuracy. The mold specification describes high-precision alignment and offers multi-cavity configurations as an option. These details matter when planning part consistency and output volume. The listed mold steel is 718H / 1.2738, with a stated service life of up to 800,000 shots; confirm that these specifications match your expected production conditions.
| Factor | Listed specification | Project check |
|---|---|---|
| Material pairing | ABS+TPU and PP+TPE | Verify the selected materials suit the part design and application |
| Alignment and cavities | High-precision alignment; multi-cavity option | Set alignment tolerances and determine whether multiple cavities are required |
| Mold construction | 718H / 1.2738 steel; up to 800,000 shots | Check suitability for the design and anticipated production volume |
| Lead time | 25–40 days | Confirm the schedule works with your project milestones |
| Quality and support | Trial run, dimensional testing, pre-shipment inspection; online technical support, maintenance, and spare parts | Agree on inspection criteria and support arrangements before ordering |
Consider how the molded part will be used when evaluating the process. Listed applications include consumer electronics shells, household appliance housings, and functional plastic components. A reported project involved a double shot overmolding mold for a French product brand's consumer electronics shell; the customer noted good alignment and stable trial samples.
Before placing an order, define the mold trial, dimensional checks, and pre-shipment inspection requirements. Longterm's ISO 9001:2015 certification covers the design, manufacturing, and sales of precision molds, as well as the sales of plastic products.
The listed examples are ABS+TPU and PP+TPE, combining hard and soft materials. Confirm the specific pairing for your design with the mold supplier.
The stated checks are a mold trial run, dimensional testing, and inspection before shipment.
The listed delivery period is 25–40 days. After-sales services include online technical assistance, mold maintenance, and spare parts supply.
Choose a process by checking material suitability, alignment tolerances, cavity needs, mold specifications, inspection steps, and delivery timing against your product requirements. Longterm offers custom double shot overmolding molds with a minimum order of one set, along with technical support, maintenance, and spare parts.
