Applications by Industry

CNC Machining Applications by Industry — Medical, Robotics, Automotive & More

Six industries drive most of our prototyping work, each with its own material, tolerance, and turnaround priorities.

JIERCHEN Enterprise Co., Ltd. (詰晟模型) has supplied prototype and low-volume parts since 1985 to 1,000+ clients across 10+ countries, including the United States, Switzerland, Sweden, Japan, and Australia. Below, each industry section pairs the typical prototyping requirement with the JIERCHEN capability that meets it — materials, process, and lead time.

Medical Devices

Medical Device Prototyping

Medical device teams need fast form/fit iteration, materials that hold up to sterilization and handling, and inspection they can put in a design history file.

JIERCHEN capability: PEEK, PC, and stainless steel machining for housings and functional components; critical dimensions verified on CMM to ±0.01mm; production under an ISO 9001 certified quality system (Certificate No. 10319/0, AFNOR). SLA models (1–3 days) support early form checks before committing to CNC machining (3–7 days).

Robotics

Robotics Prototyping

Robotics prototypes need durable structural parts, wear-resistant components at moving joints, and the ability to iterate quickly through multiple design revisions during R&D.

JIERCHEN capability: lightweight aluminum (AL6061/AL6063) for structural frames, POM and MC nylon for gears and bushings, and a process chain — SLA (1–3 days) → CNC (3–7 days) → vacuum casting (5–10 days) — built for repeated design iteration.

Case example: JIERCHEN CNC-machined structural components for a dynamic walking leg research prototype developed with UMass Amherst, supporting robotics research and demonstration hardware.

Automotive & EV

Automotive & EV Prototyping

Automotive and EV components need to survive heat, chemical exposure, and corrosion testing, often across mixed plastic-and-metal assemblies.

JIERCHEN capability: PTFE and PEEK for heat/chemical-resistant plastic parts, stainless steel and AL6061 for corrosion-resistant metal parts, finished with e-coating or anodizing for test durability. ISO 2768-f tolerance as standard.

Consumer Electronics

Consumer Electronics Prototyping

Consumer electronics prototypes need to look production-ready — tight-fitting enclosures, cosmetic finishes, and fast turnaround to keep up with design review cycles.

JIERCHEN capability: ABS, PC, and PMMA/Acrylic enclosures with polishing, hairline finish, anodizing, or silk screen printing for a retail-ready look; SLA (1–3 days) and CNC (3–7 days) keep pace with fast design cycles.

AI Wearables

AI Wearables Prototyping

Wearable device housings are compact, need a precise fit around sensors and electronics, and often move from a handful of prototypes to a small pre-production batch.

JIERCHEN capability: lightweight ABS+PC and aluminum housings machined to ISO 2768-f tolerance, with vacuum casting (5–10 days) available for small pre-production batches and cosmetic finishes such as polishing or anodizing for consumer-facing surfaces.

AI Hardware & Semiconductor Equipment

AI Hardware & Semiconductor Equipment Prototyping

AI server and semiconductor equipment teams need thermal hardware, structural brackets, and test fixtures machined fast and held to tight tolerance, without waiting on a full production tooling cycle.

JIERCHEN capability: aluminum (AL6061/AL6063) heat sink bases and liquid cooling module enclosures, PCB mounting brackets, and test and assembly jigs, plus display and cross-section models for demos — all machined to ISO 2768-f tolerance and verified on CMM to ±0.01mm. See CNC Prototyping for the full process.

Scope: We prototype the mechanical periphery — fixtures, thermal hardware, and enclosures — not semiconductor fabrication itself.
