• Lost Wax Investment Casting Advantages:

   

  Lost Wax Investment Casting Design Advantages	Lost Wax Investment Castings Cost Advantages
  Lost wax casting provides greater design flexibility Lost wax investment casting provides greater detail Near net shape Greater alloy selection to enhance part performance Surface finishes 120 to 150 RMS Close tolerances ±.005 inch per inch Lost wax investment casting results in weight reduction	Lost wax casting provides near net shape lowers material usage Reduce material costs Lost wax investment casting reduces expensive machining operations Eliminate expensive fabrications and weldments Low initial tooling costs Economic order quantities ranging from Prototype quantities to Long Production Runs

   

Quality Assurance:

Quality Control Policy

• CMI is committed to provide high quality components with competitive price. Each part will be strickly machined to the
• print. 
• CMI is committed continually improves the effectiveness of the quality management system (QMS) and sets quality 
• objectives and continuous improvement plans. 
• CMI is committed introducing all staff to its quality policy and quality systems,to familiarize themselves with the QMS 
• and strive to continue to improve upon the quality, capability and work environment. 

Detailed Quality Control In Manufacturing Process

Material Supply 

• To be sure material specification and size correct. 
• To be sure material chemical composition correct, material certification must be provided in each material purchasing lot. 

Equipment Maintain 

• Machining equipments maintain: Checked by each day, have records to track. 
• Inspection equipment maintain: Checked by each 15 days, have records to track. 

Machining Process 

• Setup work instruction chart for each part. 
• Check production process and updated drawing issue before machining. 
• Fixed Inspection: 4 times/shift, have records to check, carried by QC. 
• Random Inspection: to avoid uncertain potential quality issues. 
• Final Inspection: Each part have its final inspection stardard before packing, have inspection sheet to track. 

Packing and Assembly 

• To meet custom requirments, including labels, cartons, pallets etc before shipment.
