Overview

Zirconia ceramic rod ground to size. Zirconia is high strength, high hardness, impact resistant, wear resistant, corrosion resistant, smooth surfaced, low in thermal conductivity and non-magnetic, which is why it replaces steel shafting and guide rails in wet, abrasive and non-magnetic positions.

Key Benefits

High strength
High hardness
Impact resistance
Wear resistance
Corrosion resistance
Smooth surface
Low thermal conductivity
Non-magnetic

Problems It Solves

A steel plunger scores and loses its seal once abrasive particles get into the fluid.
Yarn cuts a groove into a metal guide, and the groove then cuts the yarn.
Steel clipper blades dull quickly and have to be resharpened or replaced.

Application Scenarios

Plungers
Ceramic shafts
Optical fiber sleeves
Ferrules
Grinding media
Ceramic cutters
Ceramic guide rails
Mechanical plunger dispensing valves

Manufacturing Process

Material And Drawing ReviewWe start from your drawing, sample or performance requirement and confirm which of the five material families fits the duty.
Powder Preparation And FormingDry pressing, hot pressing or injection moulding, chosen by the shape and the wall thickness of the part.
High Temperature SinteringParts are sintered to full density. Zirconia reaches 6.0 g/cm3 and 99% alumina reaches 3.85 g/cm3.
Grinding Polishing And CNCSurface grinding, internal and external diameter grinding and precision CNC machining bring the part to final size and finish.

Quality Control

We promise to provide quality assurance for all products. Parts are inspected according to your drawings and we issue an inspection report with the shipment.

We follow standard packaging protocols to protect your products during transit and provide photographic documentation of the packing and shipping process for your reference. In the event of transportation damage caused by non-human factors, we arrange a free replacement shipment.

From raw material preparation, forming, surface grinding, internal and external diameter grinding, to precision CNC machining, all processes are carried out in house under strict quality control.

Customisation Options

Size and shape made to your drawing
Material grade selected against the duty rather than assumed
Surface finish, including ground and polished faces
Colour where the material allows it
Metallizing and plating where the part has to braze into an assembly

Our main business is OEM and ODM. Send your drawing over WhatsApp or email and we will quote the part.

Use Guide

Confirm the fit before you order volumeTake a free sample first. Samples ship in 4 to 7 working days and we do not charge for the part, only the freight.
Give the critical dimension a toleranceCeramic is ground to size after sintering. Marking one dimension as critical is cheaper than treating them all as critical.
Handle by the body, not the edgeCeramic is hard but it chips. Zirconia tolerates handling far better than alumina because its fracture toughness is more than twice as high.
Tell us the duty, not just the shapeTemperature, fluid, load, speed, and whether the part has to insulate or stay non-magnetic, all change which grade we would quote.
