Single-material parts
Define the exact resin, geometry, fits and appearance. Review tooling release and the final-state evidence needed for the actual assembly.
PARTNER-SUPPORTED MANUFACTURING / MOLDING
Injection molding. Define the part and the tool as one project.
A molded-part offer includes decisions about resin, geometry, tooling, samples and repeat delivery. Keep the drawing, important surfaces and responsible operations visible before approving a production route.
KeepWin coordinates partner-supported review. Exact material, responsible operations, process availability, dimensions, inspection, commercial quantities and timing are confirmed in the project proposal; no universal capability or certification is promised.
Generated enclosure design study, not a validated mold design, actual production sample or evidence of a molding machine fleet.

01 / ROUTE SELECTION
Choose the molding route around the finished requirement.
A housing, an insert-bearing part and a soft-touch assembly can need different tooling and process discussions. Explain the use before selecting a label.
Inserted or overmolded features
Identify preformed components or separate material regions. Review positioning, protection, compatibility and responsibility instead of treating the assembly as one unspecified process.
Repeat variants
List part numbers, colors, materials and quantities. Compare cavity or family-tool options with the demand mix and accepted configuration.
02 / DESIGN REVIEW
Mark function before the tooling review.
The model defines shape, but release, visible surfaces and functional relationships need additional intent. Proposed manufacturability changes should be documented.
Walls and transitions
Highlight thin regions, thick sections, ribs and bosses. Review the actual resin and geometry rather than applying a universal wall or rib ratio.
Release and undercuts
Identify parting-line preferences, undercuts and important faces. Confirm the proposed tool approach and permitted changes; no mechanism is automatically available.
Gates and ejector traces
Map cosmetic and functional zones. Agree allowable locations and marks instead of assuming every surface is free of process traces.
Fits and datums
Show mating parts, assembly direction and critical relationships. Define the delivered condition and measurement basis before the tool is approved.
03 / MATERIAL & FINISH
Specify grade, appearance and delivered condition.
Resin family names do not control every property or processing behavior. Compare the exact material and physical surface reference.
| Item | Provide | Confirm |
|---|---|---|
| Resin | Exact grade, color, reinforcement or use requirement. | Offered supply, alternatives and records. |
| Appearance | Visible faces, texture and color reference. | Sample basis and permitted process marks. |
| Application | Loads, exposure and contact requirements. | Evidence for the exact grade and finished part. |
| Dimensions | Critical fits and final-state condition. | Method, sample scope and acceptance. |
04 / TOOLING SCOPE
Make tooling ownership and change responsibility explicit.
Tool preparation is a commercial and technical scope. The offer should describe who supplies, maintains and approves the tool-related work.
Supplied tooling-storage reference. It does not identify the mold for this project or establish universal ownership, capacity or service terms.
Tool definition
Confirm proposed tooling scope, responsible site, sample purpose and relevant delivery assumptions. An image of shelves does not establish tool inventory or life.
Ownership and access
Ask who owns the tool, what access or transfer terms apply and which records are supplied. Do not assume a standard ownership package.
Changes and approval
Record design revisions, permitted modifications and who approves them. Material or geometry changes may require new samples or tool work.
Repeat route
Confirm maintenance, storage and future-order assumptions where relevant. Actual capacity, minimum quantities and timing must be agreed for the proposal.
05 / ACCEPTANCE
Approve the molded configuration, not only its shape.
Sample and production evidence need a controlled material, files and surface state. A visual sample does not settle all functional questions.
| Area | Agree | Record |
|---|---|---|
| Fit | Important dimensions, datums and assembly check. | Files, method and represented sample state. |
| Appearance | Texture, color and permitted marks. | Physical reference and viewing conditions. |
| Material | Exact grade and requested identity evidence. | Named supply and applicable records. |
| Delivery | Quantity, variant and lot acceptance scope. | Identification, sampling and packing. |
06 / QUOTE PREPARATION
Price tooling, samples and finished delivery separately.
Comparable offers describe the same part, material, operations and evidence. Unit price alone may hide different tooling or acceptance assumptions.
Brief
Send units, revisions, quantities and variants, destination and target milestones. Include mandatory material, surface and documentation needs.
Breakdown
Ask for tooling, setup, samples, unit production, secondary work, inspection, records, packaging and transport to be identified where relevant.
Release basis
Define which sample or configuration approval starts the schedule. Confirm responsibility, minimum quantity, tool changes and exclusions in the actual offer.
07 / QUESTIONS
Before an injection-molding enquiry.
Keep the material, tool and acceptance in one controlled brief.
Do I need a final resin before enquiry?
Describe use and mandatory requirements if undecided. Exact material and acceptable alternatives are reviewed before approving the route.
Are molds owned by the customer?
Ownership, storage, maintenance and transfer terms must be stated in the proposal. No universal arrangement is assumed.
What tolerance, MOQ or tool life is offered?
These require project-specific confirmation against geometry, material, tool scope, quantities and evidence. No blanket numerical promise is made.
Does a sample approve all colors or materials?
Only within its recorded scope. Changes may affect appearance, processing and fit and can require further evaluation.
Are all operations in-house?
This is partner-supported review. Responsible sites and operation scope should be clarified for the offered route.
PREPARE THE NEXT DECISION
Send the part brief and the tooling decisions still open.
Include CAD and drawing revision, exact resin or application requirements, critical fits, appearance map, quantities, tooling ownership needs, sample checks and destination.
