All incoming plastic resins (such as ABS, PP, PC, Nylon, or engineering plastics) are inspected before use. This includes checking supplier certificates, verifying batch numbers, testing moisture content, and ensuring no contamination. Controlling resin quality at the start guarantees stability in molding and prevents downstream defects.

2. Mold and Tooling Inspection

Certified Plastic Materials
Before production, molds are carefully examined for wear, damage, and dimensional accuracy. Cooling channels, gates, and runners are also checked for blockages or deformation. Well-maintained molds ensure consistent part dimensions, smooth surfaces, and reduced risk of flashing or short shots.
3. Injection Molding Process Control
Key molding parameters such as injection pressure, barrel temperature, cooling time, and cycle speed are closely monitored and recorded. Stable process control reduces warpage, shrinkage, and flow marks, ensuring uniform product quality throughout the batch.

4. In-Process Visual and Dimensional Inspection

Certified Plastic Materials
Operators and quality inspectors perform regular checks on molded parts during production. This includes visual inspection for defects (sink marks, voids, burn marks, or short shots) and dimensional checks with calipers or gauges. Catching issues early prevents large-scale scrap.
5. Mechanical and Functional Testing
Parts are tested for strength, flexibility, and durability according to customer requirements. Depending on the application, impact tests, tensile tests, or load-bearing tests may be performed. Functional checks such as snap-fit engagement, threading, or assembly tests ensure usability.

6. Surface & Cosmetic Inspection

Certified Plastic Materials
Plastic parts are visually checked under proper lighting for cosmetic quality, including scratches, color consistency, gloss level, and texture accuracy. Special attention is given to customer-facing parts where aesthetics are critical.
7. Advanced Measurement & Verification
For high-precision parts, advanced equipment like CMM (Coordinate Measuring Machine), 3D laser scanners, or optical comparators is used to verify tight tolerances. This ensures dimensional accuracy for industries such as medical devices, automotive, or electronics.

8. Final Quality Assurance (QA) Inspection

Certified Plastic Materials
Each production lot undergoes a final inspection before release. Inspectors verify critical dimensions, material compliance, and performance characteristics. A quality report (including Certificates of Conformance, inspection data, or testing results) is prepared for customer assurance and traceability.

Finished parts are packed using protective packaging such as PE bags, bubble wrap, or custom trays to avoid scratches, deformation, or contamination. Pre-shipment inspection confirms correct labeling, part counts, and compliance with export packaging standards, ensuring safe worldwide delivery.

Seventh:Proactive Strategies for Injection Molding Defect Prevention
PRIME utilizes a systematic approach to defect prevention, combining precision tooling, stringent material specifications, and statistical process control (SPC) to mitigate variability and ensure component quality.
1. Sink Marks
Description: Surface dimples or depressions in thick areas caused by uneven cooling or not enough packing pressure.
PRIME Solution: The risk of sink marks can be reduced by controlling mold temperature, applying sufficient packing pressure and time, and designing parts with uniform wall thickness.
2. Short Shots
Description: A manufacturing flaw where the melted plastic solidifies before fully filling the entire mold shape.
PRIME Solution: The incomplete fill issue was resolved by optimizing the injection speed, raising the material temperature, and improving the mold's venting.
3. Flash
Description: Rust or flaking from inadequate plating, poor surface prep, or exposure to harsh environments.
PRIME Solution: Automated electroplating lines, anti-corrosion coatings, and salt spray testing extend durability and adhesion.
4. Warping
Description: A defect where the finished part is not flat or straight because some sections shrank more than others as they cooled.
PRIME Solution: Dimensional stability is achieved through balanced wall design, strategic cooling channel placement, and precise cooling time control..
5. Flow Lines
Description: These surface marks are caused by variations in how fast or how hot the plastic is as it fills the mold cavity.
PRIME Solution: To ensure the plastic flows evenly: choose the best gate location, hold a stable melt temperature, and use the appropriate mold finish.
Eighth:Choosing the Best Partner for Custom Plastic Components
Selecting the right supplier for custom metal fasteners is critical for safety, durability, and controlling long-term costs.

Procedure 5:Surface treatment
All machined parts undergo stringent quality inspections using precision measuring equipment to thoroughly verify dimensions, tolerances, and surface finishes, ensuring complete compliance with design specifications.


Procedure 6:Dimensional Validation
To meet specific application needs, we offer comprehensive post-processing options including mechanical polishing, powder coating, anodization, and other specialized surface treatments. These finishing processes simultaneously enhance both aesthetic qualities and functional performance – significantly improving corrosion protection and wear characteristics while achieving the desired visual appearance.
Procedure 7: Packaging
Upon successful quality verification, all CNC-machined components undergo protective packaging using industrial-grade materials tailored to part specifications and shipping requirements


Procedure 8: Expressing of completed goods
After completing all inspections and post-processing, the castings are finished and ready for delivery to customers or assembly into final products.
