Plastic Injection Molding

A plastic molding process where an initial molded part or substrate is further encapsulated with another plastic layer, enhancing durability, ergonomics, or aesthetics.

Overmolding

A plastic injection molding process where preformed components (usually metal) are placed into molds before molten plastic is injected, securely encapsulating the inserts within the finished part.

Insert Molding

Standard injection molding of melt-processable thermoplastic resins (ABS, PC, PA, PEEK, PP, GF-reinforced compounds) in water-cooled molds. Delivers high-cycle, recyclable parts with tight dimensional control.

Thermoplastic Injection Molding

Scientific/Precision Molding utilizes in-mold sensors and closed-loop SPC monitoring to maintain tight process control and ensure consistent part quality.

Scientific/Precision Molding

A joining technique that uses frictional heat generated by linear vibration to fuse thermoplastic parts together, often employed for large, irregularly shaped components.

Vibration Welding

Ultrasonic Welding applies high-frequency acoustic vibrations under pressure to form solid-state bonds, often used in electronics and plastics.

Engineering, Prototyping & DFM

APM’s ISO certified quality lab provides incoming, in-process and final inspection with CMM and dimensional metrology, SPC and Level 1 through 4 PPAP execution. The team supports FAI and AS9102 packages, functional and end-of-line testing, and a traceable calibration program with digital records and QMS workflows to support audits and customer-specific documentation for regulated industries.

Inspection & Quality Control (IQC) comprises the metrology, verification, and documentation activities that ensure parts conform to drawing/CAD requirements, customer specifications, and regulatory standards. IQC spans incoming, in-process, and final inspection and leverages coordinate metrology (CMMs and portable arms), laser/structured-light scanning, optical comparators and vision systems, surface-form metrology (profilometers, roundness/contour testers), nondestructive testing (NDT), and statistical process control (SPC). Results are captured in traceable reports (e.g., AS9102 FAIR, PPAP) tied to calibrated gauges and controlled environmental conditions.

Inspection & Quality Control

Dimensional Inspection verifies that a part’s physical dimensions match design tolerances. Tools include calipers, micrometers, and CMMs, ensuring geometric accuracy of length, width, height, angles, and more.

Dimensional Inspection
