Titanium Structural Bracket Details for HAL

We manufactured structural brackets for aviation control assemblies. The material required strict high-strength processing constraints, absolute tracing worksheets, and tight geometric dimensioning tolerances (GD&T) to survive extreme vibration and load strain.

Manufacturing Process

CNC Wire EDM slicing of profiles, followed by multi-axis VMC machining on the AMS 540. Final polishing and coordinate inspection reports verification.

Customer Benefits

Lightweight yet extremely stiff titanium structural details, zero structural failure logs, complete compliance with defense aircraft validation protocols.

Results Achieved

Linear dimensional tolerances held within ±5 microns. Batch delivered within a compressed 15-day timeline with a 100% quality pass rate.

High-volume CNC turned automotive spline shaft
Automotive Industry

High-Volume Splined Pinion Shaft Production

A high-volume contract run to supply drive splines and pinion axles for automotive transmission setups. Requires high rotational durability and fatigue resistance.

Manufacturing Process

Cropping onLakson bandsaws, followed by continuous high-speed CNC turning on TL20 Max 500 & TL20N setups. Precision gear spline cutting and vacuum case hardening.

Customer Benefits

High wear resistance under heavy shock loading, seamless fit in gear assemblies, significant shipping savings through localized Peenya contract sourcing.

Results Achieved

Delivered 15,000+ splined pinion shafts with zero assembly failures. Maintained surface roughness at Ra < 0.8 µm consistently.

Micron tolerance threaded steel spindle
Precision Engineering

Stainless Steel Micron-Tolerance Threaded Spindles

Production of threaded mechanical spindles used for high-speed automated packaging machines. Requires zero-play movement and high resistance to washdown chemicals.

Manufacturing Process

Precision turning on Ace Jobber XL 400 centers, custom lead-screw threading cuts, and micro-polishing of threads to reduce drag coefficient.

Customer Benefits

Zero friction sticking during continuous operation, high corrosive resistance in food-grade packaging environments, reduced motor torque strain.

Results Achieved

Coaxiality between threads and bearing seats held within 8 microns. Spindle runout was kept below 5 microns.

Heavy structural steel base frame fabrication
Fabrication Services

Heavy Structural Base Frame for Crushing Machinery

Fabrication of heavy-duty steel base foundations for material handling crushing assemblies. The structural design had to absorb severe vibrations while maintaining precise alignments.

Manufacturing Process

High-thickness plate profiling, CNC laser cutting, structural frame layout assembly, certified MIG welding, stress relieving, and epoxy paint finish.

Customer Benefits

Excellent vibration absorption, modular bolt-on design for fast site setup, long service life in harsh outdoor crushing environments.

Results Achieved

Base frames successfully tested to withstand static loads of 5.5 tons. Weld integrity checked and passed via ultrasonic NDT inspections.

Heat Treatment Equipment

SS 310 Alloy Charge Trays & Furnace Fixtures

Design and fabrication of high-temperature alloy charge baskets, grids, and retorts used in carburizing heat treatment ovens. Trays must support heavy metal parts under continuous thermal shock cycles.

Manufacturing Process

SS 310 sheet shearing, TIG structural welding using custom alloy filler wires, thermal expansion slot profiling, and fit verification.

Customer Benefits

Anti-warping frame geometry extending tray life, fast heat dispersion for energy-efficient cycles, expanded stacking payload height.

Results Achieved

Fixture lifespan increased by 180% compared to cast steel trays. Withstood repetitive cycles up to 1100°C without cracking.
