Custom Machinery Design & Special Purpose Machine (SPM) Manufacturing
Direct Answer: Sanota designs, manufactures, and commissions custom industrial machinery and automated assembly stations in Galle, Sri Lanka. Combining 3D CAD modeling, precision workshop fabrication, and automated PLC control systems, we produce high-durability production equipment tailored to your exact factory floor specifications without expensive overseas imports.
Custom Industrial Machines We Engineer
Engineered from the ground up to solve manufacturing bottlenecks that off-the-shelf equipment cannot handle.
Special Purpose Machinery (SPM)
Dedicated automated machines custom-tailored to perform specific, non-standard manufacturing operations—such as multi-axis drilling, automated folding, pressing, or winding.
Automated Assembly & Feeder Systems
Rotary dial indexing tables, pneumatic pick-and-place arms, vibratory bowl feeders, and synchronized linear conveyor lines that replace repetitive manual assembly operations.
Quality Assurance & Test Benches
Precision end-of-line test rigs with digital load cells, pressure decay leak testers, torque transducers, and automated pass/fail barcode labeling systems.
Food & Agricultural Processing Units
Sanitary stainless steel 304/316 conveyorized sorting belts, automated spice dehydrators, fruit pulping vats, and computerized liquid dosing blenders.
Hydraulic & Pneumatic Presses
Precision forming, stamping, and shearing presses featuring programmable tonnage, multi-stage pressure ramping, and opto-electronic safety curtains.
Material Handling & Transfer Gantries
Overhead automated cartesian transfer gantries, heavy roller conveyors, and custom scissor lifts optimized for cramped factory floor layouts.
How We Take A Machine Concept From CAD To Reality
Our collaborative engineering process ensures you review and approve every 3D model and mechanism before manufacturing begins.
Operational Brief & Functional Requirement
We define cycle times, throughput targets, payload weights, dimensional constraints, and operator safety requirements.
3D CAD Modeling & Kinematic Simulation
Parametric mechanical modeling in SolidWorks, structural stress calculation (FEA), and virtual 3D walkthroughs with your engineering team.
Component Selection & Tolerance Design
Sourcing premium linear guideways, ball screws, pneumatic actuators, and electric motors with high domestic availability.
Precision Workshop Machining & Fabrication
Laser cutting, CNC milling, precision lathe turning, TIG/MIG welding, and powder-coating inside our Galle workshop.
Electrical, Pneumatic & PLC Integration
Wiring of custom control panels, valve manifolds, touchscreen HMIs, and interlocking safety guard sensors.
Factory Dry Run, FAT & Site Commissioning
Rigorous test runs with actual customer materials, fine-tuning of cycle times, comprehensive manuals, and warranty signoff.
