PROJECT-SPECIFIC QUALITY CONTROL
Quality Control Built Around Your Drawings and Requirements
Quality control for custom parts begins with clear technical requirements.
Moldv reviews available drawings, CAD files, materials, critical dimensions, appearance standards, functional requirements, approved samples, inspection methods, and documentation needs before production.
Inspection activities are then planned according to the manufacturing process, component function, production quantity, project risks, and agreed acceptance criteria.
QUALITY PLANNING BEFORE PRODUCTION
Clear Requirements Create a Clearer Inspection Plan
Before manufacturing begins, the available project information should be reviewed to determine what must be controlled and how acceptance will be evaluated.
- Confirmed 2D Drawings and 3D CAD Files
- Material Grade and Applicable Material Documents
- Critical Dimensions and Tolerances
- Mating Parts and Assembly Interfaces
- Functional and Performance Requirements
- Cosmetic Surfaces and Appearance Standards
- Color, Texture, Gloss, or Transparency Requirements
- Approved Samples or Reference Parts
- Inspection Methods and Sampling Requirements
- Packaging, Labeling, and Traceability Requirements
QUALITY CONTROL STAGES
Inspection from Material Preparation to Final Delivery
Quality control is applied at different stages of the project, from technical requirement review and material verification to first-article inspection, in-process monitoring, and final release.
01 Technical Requirement Review
Drawings, CAD files, materials, tolerances, part functions, appearance requirements, and inspection expectations are reviewed before manufacturing decisions are confirmed.
02 Incoming Material Verification
Material type, specification, supplier information, quantity, appearance, and available documentation may be checked according to the agreed project requirements.
03 Tooling or Prototype Inspection
Applicable molds, fixtures, electrodes, prototypes, or initial components are reviewed before the project proceeds to trial production or sample approval.
04 First-Article Inspection
Initial parts may be measured and compared with the confirmed drawing, critical dimensions, appearance standards, assembly requirements, and reference samples.
05 In-Process Quality Control
Production conditions and selected dimensions, appearance features, assembly points, or process results may be monitored during manufacturing.
06 Final Inspection and Release
Finished components are checked according to the agreed inspection scope before packaging and delivery.
INSPECTION ITEMS AND METHODS
What Can Be Checked During a Custom Manufacturing Project?
Moldv provides integrated manufacturing solutions for consumer electronics components, including tooling, injection molding, CNC machining, silicone parts, and prototype development based on product requirements.
Dimensional Inspection
Critical dimensions, tolerances, hole positions, wall thickness, flatness, mating interfaces, and other drawing requirements may be measured using suitable inspection tools.
Appearance Inspection
Color, texture, gloss, transparency, scratches, sink marks, flow marks, weld lines, burrs, deformation, coating, printing, and cosmetic surfaces may be evaluated against agreed standards or approved samples.
Functional and Assembly Checks
Fit, movement, sealing, fastening, alignment, assembly relationships, insert retention, and other functional characteristics may be checked when applicable test conditions are available.
Material and Process Verification
Material identification, hardness, weight, molding or machining condition, secondary processing, and applicable supplier documents may be reviewed according to the project scope.
QUALITY CONTROL BY MANUFACTURING PROCESS
Quality Considerations for Each Manufacturing Process
Different manufacturing processes involve different quality risks, so inspection priorities should be defined according to the process, part function, material, and project requirements.
Electronics Mold Manufacturing
Key quality considerations may include:
• Mold structure
• Cavity and core condition
• Parting lines
• Gate and runner design
• Cooling and ejection
• Mold movement
• Surface condition
• Trial results and sample dimensions
Plastic Injection Molding
Inspection may focus on:
• Dimensions and shrinkage
• Deformation
• Sink marks and flash
• Short shots
• Flow marks and weld lines
• Color and texture
• Insert position
• Appearance and production consistency
CNC Machining
Inspection may include:
• Dimensional accuracy
• Geometric tolerances
• Hole positions
• Threads
• Surface roughness
• Burrs and edges
• Material and coating
• Fit with mating components
Rubber and Silicone Parts
Relevant inspection items may include:
• Material type
• Hardness
• Dimensions and flash
• Surface condition
• Color
• Flexibility
• Sealing interfaces
• Deformation and application performance
Rapid Prototyping
Prototype inspection may focus on:
• Appearance review
• Dimensional checking
• Assembly verification
• Customer presentation
• Functional testing
• Prototype purpose and acceptance criteria
