This pad sits between a hot or electrically live component and the surrounding fixture. It blocks heat transfer, isolates voltage, and holds its shape under load — without the machining difficulty of alumina or the temperature limits of polymer insulators.
Typical configuration: square or rectangular body, centre hole for a fastener or sensor, notched edges for location and clearance, and stepped faces where a defined gap is required. All features are cut in a single machining setup, so hole position, notch depth and overall thickness stay consistent from part to part.
Because the material is machined in its final state, no shrinkage allowance is needed. What you see on the drawing is what you get in the box.
Material: machinable glass ceramic (Macor-type equivalent)
Function: thermal barrier + electrical isolation
Finish: as-machined, fine-ground or lapped on request
Features: centre holes, edge notches, slots, steps, counterbores
Quantities: single prototypes to low-volume production
Documentation: material certificate and dimensional report on request
Drilled, milled and turned with standard carbide tooling. No sintering, no diamond grinding, no shrinkage compensation. Design changes go straight onto the next blank.
Continuous service up to approximately 800 °C depending on environment, with low thermal conductivity (around 1.5 W/mK, where applicable) to limit conduction into adjacent hardware.
High dielectric strength and stable volume resistivity at elevated temperature, so one part handles both the thermal and the electrical duty.
Fully dense, no open porosity. It will not absorb moisture or process gas, and machined dimensions do not move afterwards because there is no firing cycle.
Notches, thin webs and small holes that would need diamond tooling in 99% alumina can be cut conventionally here — useful for prototypes and low volume.
Parts are machined from the same blank stock with fixed fixturing, so batch two matches batch one without a new mould or die.
Accepted files: STEP, STP, DWG, DXF, PDF with dimensions. Quotes are normally returned within one working day.
Semiconductor equipment — insulating spacers near heated stages and chambers

Outline: square, rectangular, round, or fully custom profile
Hole pattern: single centre hole, multiple holes, slotted for adjustment
Edge features: locating notches, tabs, step-downs
Thickness: flat stock or machined step to suit your gap
Marking: laser marking for part numbers, on request
Packaging: individual bagging or tray packing for cleanroom handling
Every batch is produced under ISO 9001 certified process control, with first-article inspection on new drawings and sampling inspection on repeat orders. Critical dimensions are checked with the method agreed at quote stage — calliper, micrometer, pin gauge or CMM for tighter features.
On request we supply material certificates, dimensional inspection reports and photographs of the finished parts before shipment. If a dimension is borderline, we tell you before dispatch rather than after.
STEP, DWG, DXF or PDF. We reply within one working day with price, lead time and any manufacturability notes.
