Model features

 

Main material: ductile cast iron. The quality control: cylinder head made of nodular cast iron to ensure its strength and hardness, by forced convection and unloading unloading groove of technological measures to improve the thermal load of the cylinder body. Control precision: in six different directions with precision ruler and feeler gauge were detected, under plane maximum warpage is 0.05mm or less, use limit is 0.02mm, maximum ensures the sealed tight. Strict quality inspection and quality control system, to ensure the stability of product quality control, quality continued to improve.
