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.

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

Lost Wax Investment Casting Design, Performance & Cost Advantages

We have helped many companies find solutions to save them time, money, and headaches. Below are some examples in which we leveraged our expertise in lost wax casting to help solve various design, performance, and cost problems that had been previously unresolved for our customers:

Design Advantage
Application: Machinery Design Problem: Difficult Weldment, Poor Quality, High Manufacturing Costs Solution: Investment cast as one piece, Improved quality, Reduced cost 20%
Performance Advantage
Application: Bottling Performance Problem: Short product life, High wear, High replacement costs Solution: Changed to a cobalt based alloy, Improved product life tenfold, Reduced total costs 30%
Cost Advantage
Application: Material Handling Cost Problem: Difficult to machine, Complex shape, Unusual alloy Solution: Investment cast component, savings of 50%
