Engineering inputs
Geometry and part planning
Review supplied concepts, drawings or 3D data; clarify intended size, assembly approach, visible surfaces and the output required for downstream manufacturing.
Core manufacturing service
Custom Plastic Model Kit Manufacturing
For hobby brands, IP owners and toy companies developing injection-molded kits, ITTAK can scope support from product and engineering inputs through tooling, molding, finishing, assembly and packaging.
Product definition
This service is for plastic model kits intended for user assembly. Finished collectibles and articulated action figures follow different product and validation paths.
Project entry points
Start from the product information you have
The available inputs determine what can be reviewed now and which engineering questions should be resolved next.
- Early concept requiring feasibility and development planning
- 2D references requiring 3D or product-engineering input
- 3D or CAD data requiring part, DFM and tooling review
- Manufacturing-ready component data requiring tooling or production quotation
Available project scope
Build the scope around the product—not a generic package
ITTAK reviews which stages are already complete, which stages require support and how each handoff should be approved.
Tooling & trials
Mold engineering path
Connect agreed part data with mold construction, trial output, customer review and controlled revisions.
Production scope
Molding to packaging
Define the molding, spray painting, Tampo Print, assembly, packaging and acceptance requirements for the product.
Confirmed material capability
HIPS, ABS and PVC component production
Material choice is reviewed against part function, structure, appearance, finishing, assembly and other project needs.
HIPS
Review part geometry, runner and gate strategy, surface expectations, assembly method and decoration requirements.
ABS
Review structural loads, interfaces, dimensional requirements and compatibility with the planned finishing and assembly process.
PVC
Review required hardness or flexibility, surface finish, deformation control, decoration, assembly and packaging conditions.
Project path
From review to approved production
Manufacturing review
Share the product concept, target market, expected quantity range, schedule and available files.
Engineering alignment
Clarify parts, materials, assembly, appearance, packaging and the manufacturing scope ITTAK should support.
Tooling & trials
Define the tooling approach and how trial output, feedback, revisions and approvals will be handled.
Production & delivery
Confirm the molding, finishing, assembly and packaging activities included in the production scope.
Prepare for review
Information that makes the first conversation useful
Not every item must be final. Mark unknowns clearly so the engineering questions can be separated from confirmed product requirements.
- Product type, intended size and development stage
- Available concept, 2D, 3D or CAD information
- Expected assembly approach and part information, if known
- Material preference and appearance requirements, if known
- Expected quantity range, target timing and sales markets
- Required engineering, tooling, production and packaging scope
- Confidentiality or NDA requirement before file exchange
Commercial parameters
What affects tooling, cost and timing
Design maturity, part and tool complexity, material, finishing, assembly, packaging, quantity plan and approval cycles all influence the manufacturing plan. ITTAK reviews these factors project by project so the estimate can reflect the actual scope.

Before tooling and production are scoped
Can you review a project with incomplete files?
Yes, the current development stage can be discussed. The available information determines which manufacturing questions can be answered and what additional engineering work may be required.
Do you support snap-fit, glue assembly or mixed assembly?
ITTAK can review snap-fit, adhesive and mixed assembly designs. The recommended approach and production scope depend on the kit structure, materials and intended user experience.
When can MOQ and lead time be estimated?
An initial range can be discussed after the design maturity, required processes, quantity range and approval path are understood. ITTAK then confirms a project-specific MOQ and schedule.
