Core Process Flow

Core Process Flow

Detection Dimensions	Core Testing Equipment	Key Capability Parameters	Adaptation Scene	Core Value
Dimensional accuracy testing	Three coordinate measuring machine	1. Detection range: three-dimensional dimensions of complex parts, geometric tolerance; 2. Accuracy: ±0.001mm; 3. Advantages: automated detection, strong data consistency	1. Precision accessories for coffee appliances (spool, meter); 2. Kitchenware buckles and connectors; 3. Machining complex special-shaped parts	Accurately verify dimensional consistency, ensure parts assembly compatibility, and meet high-precision product requirements
Internal defect detection	X-ray flaw detection	1. Detection objects: internal defects of castings and welding parts; 2. Coverage: parts with wall thickness ≤50mm; 3. Identifiable defects: pores, shrinkage cavities, cracks, etc.	1. Stainless steel investment castings; 2. Welded structural parts (Pot handles, oven door frames); 3. Mechanical components with high safety requirements	Nondestructively detect internal hazards to avoid product failure due to hidden defects and ensure safe use
Material composition testing	spectrometer	1. Detection material: stainless steel, carbon steel, aluminum, Metals such as copper; 2. Accuracy: 0.001%; 3. Efficiency: rapid analysis, immediate results	1. Inspection of raw materials into the factory; 2. Finished product material verification; 3. Material differentiation in multi-material mixed production scenes	Ensure that materials comply with standards such as GB/T 1220 and eliminate problems with mixed materials or substandard ingredients.
Microscopic and performance testing	Metallographic analyzer, mechanical property testing machine, salt spray testing machine, hardness testing equipment	1. Micro: observe the microstructure of metal; 2. Mechanics: Test tensile strength and yield strength; 3. Corrosion resistance: simulate humid/corrosive environment; 4. Hardness: Quickly determine metal hardness	1. Heat treatment/welding process quality verification; 2. Corrosion resistance test of food contact parts; 3. Performance testing of highly wear-resistant parts	Verify product performance from micro to macro, support process optimization, and ensure that products meet the needs of usage scenarios.
