99.5% Alumina Ceramic Positioning Platform

01 / SEMICONDUCTOR EQUIPMENT

99.5% Alumina Ceramic Positioning Platform

Manufacturing challenge

A multi-hole positioning structure and multiple mounting faces required high flatness, bore-position accuracy and electrical insulation. Post-sintered ceramic hardness made edge chipping, flatness deformation and bore deviation critical risks.

Solution

Blank preparation → rough machining → precision grinding → finish hole machining → lapping → cleaning → CMM inspection. Staged machining and inspection controlled critical mounting faces and bore relationships.

Project result

First articles passed equipment validation and the program moved into low-volume procurement.

Capabilities demonstrated · High-purity alumina machining / large ceramic components / multi-hole positioning / high-flatness lapping / precision inspection

Zirconia Precision Ceramic Plunger

02 / MEDICAL EQUIPMENT

Zirconia Precision Ceramic Plunger

Manufacturing challenge

The customer required zirconia to replace a metal plunger that wore over time. Stable fitted diameter, roundness, cylindricity and low surface roughness were essential.

Solution

Precision cylindrical grinding → size correction → surface polishing → roundness inspection → dimensional inspection, with a fixed inspection method for repeat orders.

Project result

Samples passed assembly and endurance testing and entered stable low-volume production.

Capabilities demonstrated · Zirconia machining / precision cylindrical grinding / high surface quality / roundness control / high-precision fits

Silicon Carbide Wear-Resistant Ceramic Guide

03 / INDUSTRIAL AUTOMATION

Silicon Carbide Wear-Resistant Ceramic Guide

Manufacturing challenge

A metal guide wore during high-speed operation and affected positioning accuracy. Silicon carbide is hard and brittle, so bores, edges and mating faces required close chip and size control.

Solution

Main machining → precision grinding → mating-face machining → edge treatment → dimensional inspection → batch sampling, with optimized parameters for chip-prone areas.

Project result

Samples passed equipment validation and entered batch procurement.

Capabilities demonstrated · Silicon carbide machining / hard ceramic machining / wear components / mating faces / batch consistency

Aluminum Nitride Thermal Insulation Ceramic Plate

04 / ELECTRONICS & AUTOMATION

Aluminum Nitride Thermal Insulation Ceramic Plate

Manufacturing challenge

A high-power electronic test system needed thermal conductivity and electrical insulation, mounting bores and local grooves. The R&D quantity was small, drawings changed frequently and the material required careful yield control.

Solution

We completed a manufacturability review and proposed radius, bore-position and edge refinements. A revised drawing was supported through a second machining round.

Project result

After two design iterations, the product passed assembly validation and moved into stable low-volume production.

Capabilities demonstrated · Aluminum nitride machining / low-volume production / R&D support / design iterations / engineering communication

Macor Machinable Ceramic Vacuum Structures

05 / RESEARCH INSTRUMENTS

Macor Machinable Ceramic Vacuum Structures

Manufacturing challenge

A vacuum-analysis system needed varied low-volume, complex ceramic parts with precision bores, threads, grooves, steps, multi-face and thin-wall locating features.

Solution

Macor machining enabled CNC completion of the main structures. General-purpose workholding reduced development cost while thin walls, threads, bores and edges received focused control.

Project result

After the first-generation assembly, the customer continued purchasing multiple revised parts.

Capabilities demonstrated · Macor machining / single-piece customization / ultra-low volume / research projects / fast design iteration

Combined Metal and Ceramic Precision Components

06 / NEW ENERGY EQUIPMENT

Combined Metal and Ceramic Precision Components

Manufacturing challenge

Multiple drawing numbers, materials and processes had to be coordinated to one schedule with controlled batch quality and kit delivery.

Solution

Metal CNC machining → ceramic precision machining → grinding → surface treatment → dimensional inspection → BOM-based packing → kit delivery.

Project result

The customer reduced multi-supplier coordination and improved complete equipment-part delivery efficiency.

Capabilities demonstrated · Multi-drawing programs / multi-material manufacturing / metal-ceramic assemblies / production / kit delivery
