Injection molding materials · B2B OEM/ODM · PVC / ABS
PVC & ABS.
The material decides the mold.
Material choice drives wall thickness, undercut strategy, surface finish, steel mold design, MOQ and unit economics. This page connects the material decision to the production plan.
No material is universally better. The right choice depends on the part structure, detail, handling, compliance and expected quantity.
01 / Material comparison
Two materials.
Different behavior.
PVC and ABS are both established injection molding materials, but they solve different product problems. The final choice follows the 3D model, wall structure, finish and quantity.
Material 01 / PVC
Detail + flexibility
PVC compounds range from flexible to rigid. The material is used for fine sculpted detail, character figures and parts that benefit from more forgiving release.
- Excellent surface detail for sculpted figures
- Flexible to rigid, depending on formulation
- More forgiving around undercuts
- Good impact behavior
Best fit: character figures · collectibles · detailed toys
Material 02 / ABS
Rigid + stable
ABS is selected for rigid structures, stable dimensions, snap fits and clean molded surfaces. It is a practical base for mechanical and electronic toy components.
- Rigid, strong structure
- Stable dimensions for assembly
- Snap fits, bosses and internal features
- Clean molded surface
Best fit: model kits · playsets · electronic housings
Material names are only a starting point. Grade, formulation, wall structure and the selected process can change performance. The final recommendation follows the part review.
02 / Product types
What each material
is good at.
The product type is a useful starting point, but the final decision still follows the actual geometry, wall structure, assembly and finish.
| Product type | PVC | ABS | Why |
|---|---|---|---|
| Character figures & collectibles | Typical | Possible | PVC supports fine detail, complex sculpting and flexible release. |
| Toy vehicles & model kits | Possible | Typical | ABS offers rigidity, dimensional stability and clean assembly. |
| Playsets & structural toys | Possible | Typical | ABS is better for rigid frames, snap fits and load-bearing parts. |
| Electronic toy housings | Limited | Typical | ABS provides stable bosses, ribs and housing dimensions. |
| Flexible / soft-touch parts | Typical | Limited | Flexible PVC compounds suit parts that need give or easy release. |
| Display bases & stands | Possible | Typical | ABS gives a rigid base with stable flatness and fit. |
03 / MOQ & tooling
Material, mold
and quantity.
These three decisions are linked. A material change can change the mold; a mold change can change the MOQ and unit cost.
Injection molding carries tooling, setup and production preparation. A typical entry is 3,000 pieces per design.
Read the full MOQ guide →Higher quantities generally allocate the steel mold investment more efficiently across the production run.
See steel mold planning →
The mold is built around the material. PVC and ABS differ in shrinkage, rigidity, undercut behavior and surface requirements. Parting, draft, cooling, ejection and steel grade follow those differences. The final MOQ is confirmed after the material, part and tooling review.
04 / Decision flow
Start with the part.
Not the material name.
A material is only right when it supports the part, the mold and the production quantity. This is the review order we use.
Product function
Is the part detailed, flexible, structural, electronic or load-bearing?
Output: function briefMaterial & mold
Choose PVC or ABS, then define wall, parting, draft, undercuts and ejection.
Output: material + tooling routeQuantity & cost
Confirm the injection MOQ, tooling plan and expected production volume together.

05 / Factory-backed
Material, mold and molding
in one team.
Material review, steel mold planning, injection molding and finishing stay inside New Miho's own factory team, so the material decision is not separated from the tool and the production line.
Material review
PVC or ABS selected against function, structure and finish.
Steel mold planning
Parting, draft, cooling and ejection planned around the material.
Injection & finishing
Molding, painting, assembly and packing with the production team.
Owned factories
Mi-Ho and Boyuan are our own facilities, not external suppliers.
