Taiwan Cheng Sheng is fully equipped with precision testing instruments to analyze the physical and chemical properties of our castings as part of quality control procedures. We periodically calibrate instruments, and all our casting products are subject to documented control and follow up to ensure consistent quality. We also provide highly reliable testing rods that extract product samples to provide customers for their own inspection and analysis.

Growth at Taiwan Cheng Sheng is based on quality excellence. Our manufacturing system is dictated by strict adherence to ISO-9001 International Quality Certification guidelines practiced in our daily production routines.
Since Taiwan Cheng Sheng was established we have remained devoted to improving the quality of cast irons. Therefore we have adopted technology from Meehanite USA. Taiwan Cheng Sheng produces high quality Meehanite Cast Iron, Grey Cast Iron and Ductile Cast Iron. By combining some of the world’s top engineers with superior manufacturing and the best testing equipment available, Taiwan Cheng Sheng promises to deliver ever higher quality products that fully comply with Meehanite standards.

| GM-GA | The most versatile of the general engineering types, have a dense, fine grain structure& exceptional physical properties, including good impact strength & shock resistance.Machining to a very fine finish is recommended for heavy castings requiring pressure tightness. Both types respond to heat treatment. | Used extensively for heavy service gears, sheaves, cable drums & crane wheels, kiln tires& rollers, stamping, drawing, pressing, lathe spindles, etc. | |||||||||||
| GB-GC | A versatile iron for small & medium size castings. Relatively high density & solidity make it ideal for small types of pressure castings. | ||||||||||||
| GD-GE | A superior alternative to ordinary cast iron in all applications. Manufactured under the same strict control as all Meehanite types, ensuring structural uniformity &soundness. Improved strength & density for consistent, reliable performance. | Suitable for any size casting, from the lightest repetitive to large,heavy individual castings. | |||||||||||

| SH-SP | Ideal for relatively heavy castings where high strength is desired. | Recommended for use where severe stresses, shock or high internal pressures are encountered, e.g. heavy duty gears, sprockets,car journal boxes, etc. | |||||||||||
| SPF-SFP | In as-cast condition, has more than twice the strength of conventional gray cast iron & is exceptionally tough. Both have combined ferritic and pearlitic structure, readily machinable. Responds easily to surface hardening by nitriding or flame / electric induction heat treatment. | ||||||||||||
| SF | Exhibits high ductility, exceptional shock resistance & provides maximum toughness & machinability. | For components subjected to thermal & mechanical shock, pressure castings, valves,cylinders, automotive &machine tool parts,marine & where soft-steel castings. | |||||||||||
| SFF | ferritic structure provides maximum toughness & mechanical shock resistance. Recommended for use in subzero temperatures where shock is encountered. | Hubs, valves, clutches & pumps for use in low temp settings, e.g. wind turbines. | |||||||||||
