Integrated manufacturing partner · CIE Automotive supplier
Core to component — under one roof.
We make our own resin coated sand, shoot the cores, machine the parts and seal them against leaks — all in Chhatrapati Sambhajinagar, under one management. One partner owns every stage, so problems get fixed instead of passed around.

About Precision Engineering
Built for consistency. Ready for scale.
Precision Engineering is a manufacturing business in Chitegaon, Chhatrapati Sambhajinagar, supplying sand cores, resin coated sand and machined components to automotive customers.
Most suppliers do one step and hand you to the next vendor. We control the whole chain — from the sand that goes into the core, to the machined, leak-tested part that leaves our gate. Fewer handoffs means fewer surprises.
- Single-source accountability — one partner owns every stage
- Process consistency — sand made in-house to controlled AFS and resin specs
- Faster response — no waiting on outside sand suppliers or sub-vendors

What we do
Six capabilities, one accountable partner
Use one service or the whole chain — prototypes, development parts and volume production.
Core Making
Hot box and cold box sand cores for automotive castings, shot on 5 core shooters from sand we make ourselves. 4 more machines are on the way.
Learn moreVMC Machining
6 vertical machining centres, 3 of them with a 4th axis, for housings, brackets, flanges and pump bodies — with leak testing in-house.
Learn moreImpregnation
Vacuum impregnation that seals porosity in castings so they pass leak test — done on site, with batch records for every lot.
Learn moreConventional Machining
14+ lathes, milling, drilling and boring machines for large parts, secondary operations, prototypes and breakdown jobs.
Learn moreAluminium Gravity Die Casting Coming soon
Our new GDC unit — 2 stationary and 1 tilting machine — will add aluminium castings to the chain, made with our own cores.
