Injection Molding

Plastic Injection Molding

Custom plastic injection molded parts produced to customer drawings, with material, tooling, appearance and production requirements reviewed together.

  • Part and moldability review from customer drawings
  • Prototype and sample validation before repeat production
  • Material, color, texture and finish requirements coordinated by project
  • Secondary operations and inspection defined in the RFQ

Capability overview

Built around your drawing and functional requirements.

MIM Machining supports drawing-led plastic injection molding projects from DFM and tooling review through samples, controlled production, secondary operations and inspection. Final feasibility depends on part geometry, resin, quantity, tolerance and documentation requirements.

Project workflow

From requirements to controlled production.

01

Drawing & DFM review

Wall thickness, draft, ribs, bosses, undercuts, parting lines, gate position and ejector considerations are reviewed before tooling.

02

Tooling & sample plan

Mold construction and sample-validation scope are aligned with the drawing, expected quantity and critical requirements.

03

Molding & secondary operations

Molding, trimming, inserts, machining, printing or assembly are coordinated when they are defined in the project scope.

04

Inspection & repeat production

Approved samples and controlled drawing requirements guide inspection and subsequent production runs.

Frequently asked questions

Planning your next RFQ.

Project-specific capability depends on the drawing, material, quantity and inspection requirements.

Read the RFQ checklist
What should I send for a plastic injection molding quotation?+

Send the latest 3D model and controlled 2D drawing with resin, quantity, color or texture, critical tolerances, appearance surfaces, inspection requirements and any secondary operations.

What does the injection molding DFM review cover?+

The review considers wall thickness, draft, ribs and bosses, undercuts, parting lines, gates, ejector locations and geometry that may affect shrinkage, filling or warpage.

Can samples be reviewed before repeat production?+

Yes. Sample validation can be planned before repeat production, with the approval scope defined around the drawing and project requirements.

Can insert molding or secondary operations be included?+

Insert molding, machining, printing and assembly can be reviewed when the insert, interface, finish and functional requirements are clearly defined.
