Why buyers choose this route
Three Advantages Behind a More Controlled Model Kit Program
Precision, accumulated project experience and coordinated delivery matter most when dozens of individual parts must become one complete retail product.
01 / Engineering review
Experience becomes a better review routine.
03 / Complete pack-out
One plan continues through the complete box.
02 / Precision logic
Precision follows defined interfaces.
Product precision
Precision Is Built Into the Approval Chain
Part interfaces, assembly direction, visible surfaces, gate locations and the criteria for acceptable fit are reviewed before tooling and translated into sample and production checks.
Project experience
Regular Experience With Japanese Customers
FigCrafts has supported many custom product programs and works regularly with Japanese customers. That experience strengthens drawing discipline, change control, sample sign-off and packaging completeness.
Customer identities and protected project assets are only published when authorization permits.
Coordinated delivery
One Accountable Route From Brief to Pack-Out
Engineering, prototyping, tooling, injection, decoration, inspection and final pack-out are managed as one project plan. Instructions, printed packaging, inserts, testing or logistics can be coordinated with established providers when required.

When a Plastic Model Kit Route Fits the Project
The defining question is not simply which plastic to use. It is whether the buyer needs an organized set of molded parts that the end user assembles through a controlled sequence.
System view / Parts to complete kit
The finished product is the complete system, not one molded part.
Representative smartphone-style visualization showing how sprues, assembly, instructions and protective pack-out must agree.
Customer-Assembled Products
Parts remain organized on runners or sprues until the customer follows the defined assembly method.
Multi-Part Character or Display Kits
Authorized character, mechanical, vehicle or display concepts that require planned part separation and interfaces.
Color-Separated Kit Systems
Programs where molded colors, clear parts, decoration, decals or other visual layers must be organized deliberately.
Instruction-Led Retail Pack-Out
Every runner, loose component, instruction, printed item and package component must arrive in the correct configuration.
A model kit is a system, not only a set of molded parts.
The product is incomplete until part numbering, assembly sequence, instructions, protective packing and SKU configuration agree with the approved build.
Precision-led engineering
Control the Interfaces Before Tooling Locks the Kit
High precision is not a decorative claim. It is the result of defining what must fit, what may move, what must remain aligned and how those requirements will be approved and inspected.
Reference Geometry
Identify the dimensions, datums and visible relationships that the approved product must preserve.
Part Split and Tool Access
Divide parts around molding, release, assembly, surface appearance and the final customer build sequence.
Fit and Clearance
Define critical pegs, sockets, keys, tabs, hinges or mating surfaces according to intended assembly behavior.
Gates and Cosmetic Surfaces
Review where material enters each part and where trimming or gate evidence may affect visible surfaces.
Runner and Color Logic
Group parts around tooling feasibility, material behavior, molded color, production control and pack-out needs.
Sample and Production Checks
Convert the approved build into fit, appearance, runner, quantity and completeness checkpoints.
What precision means
Different Kit Features Need Different Controls

Primary review
Approval evidence
Material logic
Materials Follow Part Function and Assembly Behavior
A material name alone does not define a reliable model kit. Selection is confirmed by part function, interface behavior, appearance, production method and applicable testing requirements.
Material behavior / 1–5
Each zone asks a different engineering question.
The five panels correspond to structure, interface stress, clarity, flexibility and decorated-surface behavior.
Rigidity and Surface
Dimensional stability, molded detail, visible finish, gate location and decoration compatibility.
Fit and Stress
Insertion force, retention, repeated assembly behavior, stress concentration and part geometry.
Appearance and Protection
Clarity, tint, stress, surface marks, separate handling and protection inside the package.
Flexibility and Clearance
Bending behavior, assembly order, collision risk and the effect on adjacent finished surfaces.
Adhesion and Finish
Surface preparation, printing, paint, decal placement, rub areas and approved visual consistency.
Approval-led development
From Authorized Assets to a Complete Kit Pack-Out
Each stage closes a specific risk before the project advances. The exact route is confirmed after the starting files and finished-product requirements are reviewed.

Six approval gates keep the project connected.
Brief and Rights Review
Confirm authorization, target size, assembled product, quantity, market, SKU plan and packaging direction.
3D and Kit Engineering
Develop part architecture, interfaces, assembly sequence, runner logic and visible-surface priorities.
Prototype and Build Review
Check form, fit, assembly behavior, handling, appearance and the criteria the sample must prove.
Tooling and Trial Parts
Prepare tools, review trial parts, correct critical issues and confirm runner and part condition.
Injection and Decoration
Mold approved parts, apply confirmed printing or finishing and control variants through the production plan.
Completeness and Pack-Out
Verify runners, loose parts, printed items and SKU configuration before final packing and shipment release.
Coordinated one-stop service
One Project Team Coordinates the Complete Delivery Plan
The advantage is continuity: engineering decisions remain connected to tools, molded parts, approvals, instructions, packaging and the final kit configuration.

Quality at kit level
Inspect the Build and the Completeness of the Box
A visually acceptable part can still fail the product if it does not fit, appears on the wrong runner, is missing from the BOM or reaches the wrong SKU pack-out.
Quality view / Fit + identity + completeness
Part condition, assembly and the final box are checked as one product.
Representative smartphone-style visualization, not an inspection record or customer shipment.
Tool and Trial-Part Review
Review part formation, visible defects, gate condition, critical dimensions and tooling corrections against the approved criteria.
Assembly and Fit Review
Build the defined sample sequence and check alignment, insertion, retention, interference and finished appearance.
Runner and Variant Control
Confirm runner identity, molded color, loose components, SKU assignment and approved production configuration.
Final Completeness Check
Verify BOM, instructions, printed items, protective components, package version and carton quantities before release.
FAI, sampling plans, buyer inspection and third-party testing are applied only when defined in the approved quality plan or project agreement.

Use when the buyer receives a finished assembled collectible where sculpt, surface, decoration and display condition lead.
Review static figure route →Commercial and engineering questions
Resolve the Product Boundary Before Tooling
These answers define the normal review route without replacing the approved drawings, quality plan or project agreement.
What files should we send for a model kit review?
Send the authorized artwork or 3D files available, assembled size, quantity, target market, reference build, known part or runner plan, assembly method, colors, decoration, instructions, packaging and schedule. Missing items can be identified during the initial review.
Can you develop snap-fit and glue-assembled kits?
Both routes can be reviewed. The suitable construction depends on geometry, part size, interface behavior, material direction, user assembly expectations, appearance and the approved production method.
What is the typical MOQ for injection production?
A typical injection production MOQ is 500–1,000 units after engineering review. The confirmed quantity depends on the part and tooling scope, material, runner and color plan, decoration, SKU split, packaging and the quantity per version.
Can a model kit use different colors, clear parts or functional materials?
Yes, when the approved product and production route support them. Runner grouping and material selection are confirmed by part function, interface behavior, appearance, tooling, production control, packaging and applicable testing requirements.
Can you support instructions, decals and retail packaging?
Yes. FigCrafts can coordinate the instruction, printed component, decal, label, tray, box and carton requirements as part of the approved pack-out plan. Partner-produced components are identified within the project scope, and final assembly, inspection and pack-out can be completed on-site.
How do you control high-precision fit?
Critical interfaces are defined through the product geometry, function, material behavior and assembly method, then reviewed through engineering, tooling, trial parts, approved samples and production inspection. Numerical tolerances are confirmed for the specific project rather than published as a universal promise.
Do you have experience with Japanese customers?
Yes. FigCrafts has regular experience supporting Japanese customer programs and other international custom manufacturing projects. Customer names, protected designs and project images are only published when the necessary authorization is available.
Can we sign an NDA, and how are tooling terms handled?
NDA support is available before detailed file exchange. Tooling ownership, storage, maintenance, use and transfer terms are confirmed in the project agreement before tooling begins. Customer-funded tooling arrangements are documented as part of the approved commercial scope.
What affects the project timeline?
The schedule depends on the starting file quality, part count, assembly complexity, prototype route, tooling scope, runner and color plan, sample revisions, decoration, instructions, SKU count, packaging readiness, testing and approval response time. A project schedule is prepared after the route and approval gates are defined.
Can you support market-specific testing?
Testing can be coordinated according to the product, materials, age grading, target market and agreed test scope. EN 71, ASTM F963, CPSIA, REACH or another standard is not presented as a universal compliance claim for every model kit.
