Product Description

Forged Steel Crankshaft for Piston Reciprocating Compressor

A crankshaft is a fundamental and critical component of an internal combustion engine or compressor. Its primary function is to convert the reciprocating linear motion of the pistons into rotational motion. This rotational force (torque) is then transmitted through the drivetrain to ultimately propel the machine.

Manufactured from high-strength forged steel and precision-machined to exacting tolerances, it is engineered for durability, reliability, and optimal performance under extreme conditions.

Machinery Processing

Forging Blank and Inspection

Steel billet is heated to high temperatures for malleability.
Pressed into a die under immense force for the rough shape.
Excess material (flash) is trimmed off.
Inspection: PT detects surface flaws like cracks or porosity.

Finishing Process

Achieves exact dimensions and a mirror-like surface finish on journals and crankpins. Uses specialized grinders and fixtures for extreme stability and precision. Ensures minimal friction and superior durability.

Counterweight & Dynamic Balancing

Minimizes harmful vibrations during operation.
Reduces noise and stress on bearings.
Enhances overall performance and longevity.

Frequently Asked Questions

What are your core machining capabilities?

We are equipped with modern CNC machine tools, including three-axis, four-axis, and five-axis machining centers, milling machines, and grinders. We can handle highly complex parts ranging from simple shafts to large-scale industrial components.

How do you ensure the quality of forged parts?

We implement a multi-faceted inspection process including visual checks, dimensional measurements, and non-destructive testing (UT and PT). Our forgings meet EN10228-3-1998 or GB/T6402-2008 Grade 3 standards.

Can you handle design challenges from provided drawings?

Yes, we offer DFM (Design for Manufacturing) analysis to identify potential issues early and suggest modifications that reduce costs while improving the structural integrity and manufacturability of the part.

What materials do you typically work with?

We primarily use high-quality forging steel (such as Steel 45) and other customized alloy steels, ensuring better internal purity and density compared to continuous casting billets.

What is the collaboration process for new projects?

The process includes an initial inquiry with drawings, a technical DFM review, formal quotation, production with regular updates, final quality inspection, and secure packaging for delivery.

How is the product protected during international shipping?

We use tailored, robust protection including comprehensive wrapping, shock-absorbing materials, environmental sealing against moisture, and secure wooden crates or steel frames.
