Incoming Quality Control
During this Incoming Quality Control stage, we focus on two key actions. One is to ensure all compressor parts are from world-renowned suppliers, and the other is to check carefully on all the incoming materials & Parts
Renowned Suppliers SelectingComair dynamically evaluates all the suppliers to ensure only renowned and trustworthy ones are in the repository. For the key components like the air end and engine, only the leading players could supply to us, including GHH and Cummins.
Quality Checking & Monitoring100% of raw materials and parts are under strict and systematic supervision and checking by our quality control team. High-accuracy tools will be used to measure the parts, and we will have a detailed tracing, recording, and filling system. Only the qualified parts will be used for our compressors.
In-Progress Quality Control
In-progress Quality Control is the core stage, which accounts for 90% of compressor manufacturing defects. Comair has four specific control procedures in this stage, which include: Highly Advanced Processing Equipment, Manufacturing Engineers Team, Specially Delegated Inspection Staff, and Energy Efficiency Testing.
Highly Advanced Processing EquipmentWorld renowned processing equipment has been used for the production and inspection of key components including screw rotors and impellers. Compressors are usually required to continuously operate at high speeds for long periods of time. So screw rotors or impellers shall be of extremely high accuracy to u class.
Manufacturing Engineers TeamBefore each manufacturing and assembly process, our engineers team will review our internal Standard Operation Procedures. So we can ensure all the parts are fixed and installed strictly according to the standards.
Specially Delegated Inspection StaffAfter assembly, our specially delegated inspection staff will undertake a thorough visual inspection and make a detailed recording. Inspection work will include checking the oil level, air end installation, nut fixing, piping connecting, etc.
Energy Efficiency TestingComair has built a professional Compressor Energy Efficiency Testing Center. Before delivery, all the compressors will be tested against engineering specifications, customer requirements, and our manufacturing standards. If required, the clients could join a video conference to see the compressors testing and running.
Outgoing Quality Control
During this quality control stage, we have three procedures ensuring the best compressor quality delivery. They are Systematic Pre-shipment Inspection, Delivery Cleaning & Anti-rust Treatment, and Sea Worthy Packing.
Systematic Pre-Shipment InspectionAfter the compressors are tested and before delivery, our quality control team will further conduct systematic inspections on pipes, appearance, PLC settings, and electrical parts, etc.
Delivery Cleaning & Anti-Rust TreatmentWe will conduct a complete and thorough cleaning of compressors. For all the exposed parts, we will make the anti-rust treatment so as to ensure the longest lifespan.
Sea Worthy PackingAll the export compressors will be properly packed and protected in the export standard sea-worthy packing materials.
