A slaughter line runs six or seven days a week under water, blood, fat and constant washdown. Equipment that is merely “acceptable” at delivery becomes a maintenance problem within a year. Zhengye’s quality control is built around one question: will this machine still run true after years of slaughterhouse duty?
Material Control and Traceability
Food-contact parts are built from food-grade stainless steel, and every material batch is logged at receiving. Plate, tube and section are checked against mill certificates before they enter the workshop, so the steel in a scalding tank or an evisceration conveyor can be traced back to its batch if a question ever arises. Carbon steel structures are sandblasted and coated for corrosion resistance in wet environments.
Welding Standards
Welding is where slaughter equipment succeeds or fails. Frames and tanks are welded by certified welders following defined procedures for each material and thickness. Food-contact welds are ground smooth and polished, eliminating the crevices where bacteria and residue accumulate — a detail that matters both for hygiene inspection and for halal audit. Critical structural welds are visually inspected, and load-bearing welds on rails, hoists and killing boxes are checked against drawing requirements before assembly.
Component Selection: Motors, Gearboxes and Electrics
We select drive components for availability in your market as much as for performance. Motors and gearboxes come from established brands with service networks in Southeast and Central Asia, and electrical cabinets are built with components that local electricians can source. Every panel is wired and labeled in English, configured for your voltage and frequency, and tested under power before packing. Pneumatic and hydraulic components follow the same rule: proven brands, standard seals, locally replaceable.
Testing Before Dispatch
Every machine passes a defined test sequence before it is released for packing:
- Dimensional check — measured against the approved drawings, including conveyor heights, rail spacing and interface points
- No-load running test — conveyors, dehairers, hide pullers and saws run under power to verify alignment, noise and drive behavior
- Water-pressure test — scalding tanks and water-bearing equipment are filled and checked for leaks
- Hydraulic and pneumatic pressure test — killing boxes, hide pullers and restraint systems are cycled under load to verify seals, valves and safety interlocks
- Electrical test — panels are energized, controls and emergency stops verified, and wiring checked against the schematic
Factory Acceptance Test (FAT)
For turnkey lines, we run a factory acceptance test before shipment: key line sections are pre-assembled and operated, and you are invited to witness the FAT in person or by live video. Punch-list items are closed in the factory — where we have the welders, the stock and the tooling — instead of on your site. FAT records and test videos form part of the project documentation you receive with the equipment.
