Introduction: ODM programs often begin with a function, appearance concept, sample, or market requirement and require more design collaboration than build-to-drawing manufacturing. Development scope, design responsibility, fees, sample stages, change rules, and intellectual-property ownership must be agreed before formal work begins.
Introduction: OEM programs are based on drawings, specifications, and brand requirements that the customer owns or is authorized to use. Within the written scope, we can support tooling, precision components, trials, or injection molding, with agreed controls for revisions, inspection, changes, and delivery.
Introduction: Pre-tooling review identifies issues that may affect manufacturing, appearance, dimensions, and assembly. A useful DFM is not a one-line statement that a part can be molded; it documents risks, recommendations, assumptions, and open decisions.
Introduction: Low-volume runs are useful for new product introduction, design verification, assembly checks, and market evaluation. The purpose is to confirm the product and process before scale-up, not to replace production criteria with temporary conditions.
Suitable stages: Design verification after initial samples, engineering-change validation, new material or color trials, and low-volume confirmation before production launch.
Introduction: SHIYUNJIA supports trial and production molding for reviewed plastic component programs. Before production, both sides should agree material, color, approved sample, cosmetic criteria, critical dimensions, packing, and lot requirements.
