Separate the material from the manufacturing method
A product brief that says only PVC figure leaves important questions unanswered. Vinyl commonly refers to PVC-based material, while slush molding describes a way of forming hollow parts. Injection molding is a different route for producing shaped components. A material family may appear in more than one process, so request the proposed process and construction together.
UCHOTEN FACTORY's published soft-vinyl workflow illustrates filling a metal mold, heating, removing excess material, further heating, cooling and trimming before decoration and assembly. That is a useful reference for understanding hollow soft-vinyl production. It does not establish ITTAK's exact equipment, formulation, settings or available effects, which must be confirmed separately.
Compare the route against the product experience
Begin with what the customer will receive and do with the figure. A display-oriented designer toy, an articulated character and a set of fitted accessories can have different priorities even when their silhouettes look similar. The table identifies questions for a supplier review, not a fixed rule that one process can or cannot make a particular shape.
| Review topic | Slush-molded vinyl proposal | Injection-molded proposal |
|---|---|---|
| Part construction | Confirm hollow sections, openings, trimming and joins | Confirm component breakdown, mold opening and assembly |
| Handling and movement | Review material feel, shape recovery and any intended movement | Review material pairing, fit and joint requirements where applicable |
| Surface appearance | Agree molded colors, paint boundaries and finish samples | Agree molded colors, gate/seam locations and decorated samples |
| Accessories | Check how separate pieces connect to the figure | Check mating features and any interchangeable components |
| Commercial comparison | Identify tooling, finishing, assembly and packing scope | Identify tooling, finishing, assembly and packing scope |
Use sofubi as a qualified description, not an origin shortcut
Buyers may search for sofubi, sofvi, soft vinyl toys or designer vinyl figures. These searches can overlap, but the terminology does not settle the country of manufacture or the exact process. If your brand brief uses sofubi, describe the intended material feel, construction, appearance and manufacturing expectations explicitly instead of relying on the word alone.
Do not describe a new product as Japanese-made merely because it follows a soft-vinyl aesthetic or because the manufacturer works with Japanese customers. Ask the supplier to confirm origin and the scope of any requested process description before using them in packaging or marketing. ITTAK's vinyl service page is a manufacturing inquiry route, not a claim of Japanese origin.
Approve construction and decoration in separate checks
Review an undecorated sample for the intended shape, joins and handling before using a painted sample to settle appearance. For a hollow figure, discuss how the bottom or other openings are finished and how the figure stands. For an assembled figure, check every supplied connection. If movement is expected, state whether it is occasional positioning or a central product feature.
Mark paint boundaries, exposed molded-color areas and the surfaces that can contact one another during assembly or movement. Ask how the agreed finish will be assessed after the product is assembled. Include the packaging in sample planning: an approved display sample does not automatically show that the packed product will retain its intended shape and finish through the proposed distribution route.
Ask for alternatives with the same delivery scope
Share size, views of the design, quantity plans, colorways, accessories and the required delivered state. Separate an unpainted figure request from a fully decorated and packed product. If you want both processes considered, ask suppliers to explain the changes to part design, tooling, sample approvals and finishing rather than returning two unexplained unit prices.
Keep initial quantities and possible reorders distinct. A later colorway may reuse some development decisions, but decoration and packaging still need review. ITTAK confirms the process, sample plan, price and minimum order quantity per project. Its confirmed in-house HIPS, ABS and PVC component production does not mean every process described in this guide is automatically performed in-house.
Common buyer questions
Are all vinyl figures made by slush molding?
No. Vinyl is a material description, not a complete process specification. Ask whether the proposal uses slush molding, another hollow-forming method or injection molding, and review the actual construction and sample.
Does sofubi mean the figure is manufactured in Japan?
The term alone is not sufficient evidence of origin. Confirm the manufacturing location and process with the supplier, then describe the product accurately. ITTAK does not use a sofubi-related inquiry as a claim of Japanese manufacture.
Which route has the lower MOQ or cost?
There is no universal answer for a finished custom figure. Tooling, part count, decoration, quantity and packing all affect the proposal. Request comparable quotes for the same delivered product; ITTAK does not publish a standard MOQ or price for every design.
