Inspected By Dynamice Balancing Test Dedicated Stainless Steel Sleeve Of Aluminum Foil Mill Machine

Product Application

The 304 stainless steel sleeve is a precision rotating component used in aluminum foil rolling equipment. Depending on the mill configuration, it can be used for roll support, torque transmission, and positioning. Because the sleeve operates as a rotating component, concentricity, dimensional accuracy, surface quality, and dynamic balance are important manufacturing requirements.

GW Precision pays particular attention to sleeve concentricity during manufacturing. Accurate control of the inner and outer surfaces helps maintain stable assembly and rotation, supporting reliable operation of aluminum foil rolling equipment.

Material and Centrifugal Casting

The specified material for this sleeve is 304 stainless steel, with a product size of 355 × 305 × 1300 mm. According to the supplied ASTM A240/A240M reference, typical 304 stainless steel contains 18.0–20.0% chromium and 8.0–10.5% nickel, with carbon controlled to ≤0.08%.

GW Precision obtains sleeve blanks through centrifugal casting. Controlled melting and casting processes are used to help reduce common casting defects such as cracks, slag inclusions, pores, and sand holes. After casting, the sleeve blank is processed through subsequent machining and inspection procedures.

Precision Machining and Concentricity Control

Precision machining is a key stage in sleeve manufacturing. The machining process is arranged according to the sleeve drawing, dimensions, and required accuracy. Particular attention is given to the inner hole, outer diameter, concentricity, and critical mating surfaces.

Accurate machining of the sleeve helps maintain the required geometric relationship between rotating surfaces. This is especially important for aluminum foil mills, where stable rotation contributes to equipment operating stability and rolling quality.

Dynamic Balance Testing

Dynamic balance testing is used to evaluate the rotational stability of the finished sleeve. For high-speed sleeve applications, the supplied technical requirements include multi-speed testing, such as calibration at 500, 1000, and 1500 rpm.

The dynamic balance level may be specified within G1.0–G2.5 according to ISO 1940, depending on the actual application and customer requirements. Dynamic balance correction is combined with precision machining and dimensional inspection to control the rotating condition of the sleeve.

Heat Treatment and Quality Control

GW Precision conducts heat treatment when specific mechanical properties are required. The treatment process is determined according to the material condition and customer technical requirements, followed by the necessary inspection.

Quality control covers material, dimensions, machining condition, and dynamic balance requirements. The combination of centrifugal casting, precision machining, heat treatment when required, and dynamic balance testing provides a controlled manufacturing process for customized sleeves.

Customized Manufacturing

GW Precision has qualified technical personnel, an established management system, and an annual sleeve production capacity of approximately 4,000 sets. Customized sleeves can be manufactured according to customer drawings, dimensions, material requirements, and application conditions.

The company's sleeves are supplied for aluminum foil, sheet, strip, and other rolling industries. Through controlled manufacturing and inspection processes, GW Precision provides customized sleeve solutions for different rolling mill applications.
