Company Overview

Long block production of automotive engines is a complex multi-step process, including casting, precision machining, component pre-assembly and final assembly. This article details the key technologies, quality control methods and final inspection process of long block engine production in each step. Whether it is an aluminum or cast iron engine, all parts must meet strict tolerance standards to ensure the efficiency and durability of the engine.

The engine cylinder head is one of the key components of the engine, responsible for sealing the combustion chamber and controlling airflow and heat dissipation. The production process of the cylinder head includes design, casting, heat treatment, precision machining, valve seat and guide installation, and final inspection and assembly. Through strict quality control and testing, we ensure that each cylinder head meets the standards before assembly to ensure the efficient operation and durability of the engine.

The engine crankshaft is a key component that converts the linear motion of the piston into rotational motion. Its production process involves design, forging or casting, heat treatment, precision machining and surface treatment. Through dynamic balancing, surface hardening and strict quality inspection, the strength, wear resistance and reliability of the crankshaft are maximized to ensure the stable performance of the engine under high load.

The engine camshaft is a key component that controls the opening and closing of the intake and exhaust valves. Its production process covers multiple steps from design, material selection, casting or forging to precision grinding and heat treatment. After strict balancing, surface treatment and quality testing, the camshaft can provide precise valve control to ensure efficient operation and long-term durability of the engine.
