Portable and handheld devices
Precision housings, structural components, buttons, bezels, endcaps, retainers and internal mechanical parts.
PROCH Plastic Co., Ltd. integrates precision CNC machining, plastic injection molding, surface treatment coordination, inspection and assembly for medical device component projects from prototype to controlled production.



PROCH is a suitable manufacturing partner when a project requires metal and plastic components, coordinated tolerances, documented inspection and assembly support.
Precision housings, structural components, buttons, bezels, endcaps, retainers and internal mechanical parts.
Custom components and enclosures requiring dimensional control, cosmetic control and repeatable assembly fit.
Metal and plastic parts coordinated through inspection planning, fixtures, subassembly and production transfer.
A single engineering interface helps medical-device teams manage cross-part fit, cosmetic expectations and production-transfer evidence without repeating the full equipment information maintained on the Manufacturing page.
Metal and molded mating parts are reviewed together so stack-up, fastening, clearance and assembly risks can be identified before production release.
Dimensional requirements, surface finishes, colors and appearance criteria can be coordinated against the same approved product intent.
Approved drawings, CTQs, inspection methods, fixtures and process conditions support a clearer handoff from prototype and pilot builds to repeat production.
The Manufacturing page is the authoritative source for machining, molding, inspection, assembly and production-control capabilities.
Each phase converts customer requirements into reviewed specifications, process conditions and traceable production evidence.
Share a non-confidential summary first, or arrange an NDA before exchanging technical files.
Quality-system, manufacturing and traceability records can support customer technical reviews and supplier-control activities within an agreed disclosure scope.
ISO 9001 and ISO 13485 certificates, quality manual information and procedure lists within the agreed disclosure scope.
FAI, inspection reports, CPK records where required, material or process records and nonconformance follow-up.
Calibration, training, document control, traceability examples and onsite or remote audit support under NDA.
The FDA Quality Management System Regulation (QMSR) became effective on February 2, 2026 and incorporates ISO 13485:2016 into the quality management system requirements of 21 CFR Part 820. Medical device manufacturers remain responsible for meeting QMSR and other applicable FDA regulatory requirements. ISO 13485 certification does not constitute FDA approval and does not replace an FDA inspection.
FDA QMSR FAQISO 9001 and ISO 13485 certificate images are maintained on the About PROCH page so customers can review the published certification source without duplicated files.
Yes. Integrated CNC machining and plastic injection molding help coordinate fit, tolerance and production requirements across both component types.
Operations are supported by ISO 9001 and ISO 13485. Confirmed capabilities include CPK ≥ 1.33 for agreed CTQs, 1 µm CMM resolution and C=0 AQL 0.4–1.0. Applicable sampling levels are selected according to product and customer quality requirements.

Provide 2D/3D data, material, quantity, finish, sample requirements, CTQs, inspection and assembly requirements, and target schedule where available.
Complete information helps engineering evaluate manufacturability, inspection scope, lead time and commercial assumptions earlier.
