Our Heritage & Philosophy

Industrial Machinery Built for Heavy 24/7 Factory Shifts

CV. Sentosa Teknik was established with a clear engineering objective: to provide Indonesian food producers with heavy-duty industrial machinery that matches the build quality of imported lines while offering local workshop support, accessible spare parts, and custom fabrication tailored to local dough recipes.

Unlike general fabrication shops, we specialize exclusively in the cracker manufacturing ecosystem and thermal energy generation. We understand that a cracker factory requires seamless synchronization: high-viscosity tapioca mixing, continuous dough sheeting, calibrated flower moulding, temperature-controlled steam cooking, razor-sharp slicing, and uniform drying. A failure in one stage halts the entire line.

Our Sidoarjo workshop is equipped with precision machinery including CNC plasma cutting beds, 200-ton hydraulic press calenders, heavy-duty industrial lathe turning machines, and sanitary argon TIG welding bays. Every pressure vessel and steam boiler is built to ASME standards and certified through rigorous 1.5x hydrostatic pressure testing witnessed by certified Disnaker safety inspectors.

Facility 01

CNC Plasma & Machining

High-accuracy CNC cutting and machining ensure structural frames, gears, and dough rollers align within 0.1 mm tolerances.

Facility 02

Sanitary TIG Welding

Smooth, crevice-free argon TIG welding on all food-contact SS304/SS316 surfaces prevents bacteria traps and dough stagnation.

Facility 03

Boiler Hydrostatic Bay

Dedicated test bay for pressure testing boiler vessels at 1.5x design pressure (15–20 bar) witnessed by government inspectors.

Facility 04

Pre-Shipment FAT Trial

Live testing zone where clients bring real dough batches to verify mixer torque, cutter sharpness, and output yield.

Engineering Scope

Comprehensive Processing Lines from Raw Starch to Finished Crisp Cracker

Industrial High-Torque Dough Mixers

Sanitary Double Ribbon & Z-Blade mixing units engineered specifically for dense tapioca, starch, and seasoning doughs. Features hydraulic tilt discharge and VFD speed inverter.

Precision Sheeters & Automated Formers

Multi-stage calender rolling tables, automatic flower cracker moulders, and cylindrical log extruders providing uniform thickness and exact grammage calibration.

Certified Industrial Steam Boilers

3-Pass wetback fire-tube boilers (0.5 to 3.0 tons/hr) operating on natural gas, solar diesel, or biomass. Equipped with dual safety relief valves and Disnaker licensing.

Continuous Steam Chambers & Slicers

Direct-steam gelatinization cooking tunnels and ultra-accurate guillotine cutters producing uniform slices without fracturing or dough waste.
