OPC Drum Aluminum Tube

An OPC drum aluminum tube is a high-precision aluminum base tube used in photosensitive drum assemblies for laser printers, copiers, and other electrophotographic equipment. Compared with ordinary industrial aluminum tubes, OPC drum aluminum tubes require tighter control of outside-diameter tolerance, roundness, straightness, radial runout, and outer-surface quality to accommodate subsequent photosensitive-layer coating, drum machining, and high-speed rotation.

Henan Chalco Aluminum can supply high-precision seamless OPC drum aluminum tubes and customize the OD, ID or wall thickness, length, dimensional tolerances, roundness, runout, surface roughness, and end machining according to the customer's product model or drawings. In addition to precision aluminum base tubes, we can provide OPC photosensitive coating, supporting continuous supply from seamless tube production, precision drawing, surface treatment, and cut-to-length processing to photosensitive-material coating and inspection.

OPC Drum Aluminum Tube Specifications

OPC photosensitive drum dimensions vary with printer and copier models and drum assembly designs, so the aluminum base tubes are generally produced to customer specifications or drawings. In addition to the basic OD, wall thickness, and length, roundness, runout, straightness, surface roughness, and end configuration can be further specified.

Alloy: 6063 / 3003

Tube Type: High-Precision Seamless Aluminum Tube

Typical OD: Approx. 20-60 mm

Typical Length: Approx. 200-300 mm, or cut to length to drawings

Process: Seamless Extrusion + Precision Drawing

End Processing: Cut-to-Length / Chamfering / Deburring

Surface: Precision drawn, smooth, and clean

For different printer, copier, and photosensitive drum models, the OD, ID or wall thickness, length, OD tolerance, roundness, straightness, radial runout, surface roughness, and end configuration can all be customized to customer drawings.

OPC Photosensitive Coating

In addition to high-precision OPC drum aluminum tubes, Henan Chalco Aluminum can provide OPC photosensitive-material coating to form an organic photoconductive photosensitive layer on the conductive aluminum base tube. The coating can be customized according to the customer's photosensitive drum model, operating requirements, and coating specifications.

Surface Pretreatment

Before coating, the aluminum base tube can be cleaned and pretreated to control oil, metal particles, and processing residue, providing a uniform, clean substrate surface for OPC photosensitive-material coating.

OPC Coating

OPC photosensitive-material coating can be applied according to customer requirements, with control of coating uniformity, continuity, and surface appearance. For projects with an established OPC formulation or coating specification, production can be organized according to the applicable requirements.

Flexible Delivery

Customers can select high-precision uncoated aluminum base tubes according to their own production process or purchase products after OPC photosensitive coating. For sample validation and volume projects, a suitable solution can be provided based on tube specifications, surface condition, coating requirements, and final delivery condition.

Aluminum Alloy Options

Henan Chalco Aluminum can supply 6063, 3003, and other OPC drum aluminum tubes. A suitable alloy and temper can be selected based on photosensitive drum dimensions and requirements for precision drawing, machining, and subsequent surface treatment.

Manufacturing and Machining

Henan Chalco Aluminum can supply OPC drum aluminum tubes from seamless tube hollows and precision drawing through cut-to-length and end machining. Continuous process control covers tube dimensions, roundness, straightness, and surface condition, while finished dimensions are machined to customer drawings.

Billet -> Seamless Extrusion -> Precision Drawing -> Straightening -> Cutting -> Chamfering / End Machining -> Cleaning -> Inspection

Seamless Extrusion

Aluminum tube hollows are produced by seamless extrusion, creating a continuous tube body without a longitudinal weld and providing a stable basis for subsequent precision drawing and small-diameter, thin-wall processing. The extruded tube-hollow specification can be selected according to the final OPC aluminum tube dimensions.

Precision Drawing

Precision drawing further controls the OD, ID or wall thickness, roundness, and surface condition, while straightening improves tube straightness. For OPC aluminum tubes with specified tolerances, roundness, runout, or surface-roughness requirements, the corresponding drawing and finishing process can be matched to the drawings.

After drawing and straightening, the tube can be precision cut to the finished OPC drum length, with end-face treatment, internal and external chamfering, and deburring. End bores, steps, or other structures can also be machined to drawings. After machining, the tube is cleaned and dimensionally inspected and can be delivered as a cut-to-length precision aluminum base tube, reducing subsequent basic processing operations.

Quality Assurance and Stable Supply

Henan Chalco Aluminum includes dimensional accuracy, surface quality, batch consistency, and product traceability in the quality-control process for OPC drum aluminum tubes and can support sample validation, small-batch trials, and long-term volume supply.

Precision and Surface Control

Key dimensions and geometric accuracy, including OD, ID, wall thickness, length, roundness, runout, and straightness, can be controlled according to customer drawings. Surface items such as roughness, scratches, draw marks, dents, pressure marks, and cleanliness can also be inspected.

For projects with specified Ra, tolerances, roundness, runout, or surface-defect criteria, production and inspection can be organized according to the customer's technical specifications.

Inspection and Traceability

Finished products can be inspected for dimensions, geometric accuracy, surface condition, and end machining, with traceability based on material batches, production batches, and inspection records. Material certificates, dimensional inspection reports, and related quality documents can be provided according to order requirements.

Batch Consistency

For long-term fixed models, repeat production can be arranged according to approved drawings and technical requirements. Dimensions, roundness, runout, surface condition, and end-machining consistency are continuously controlled for recurring volume purchases of OPC drums.

Protective Packaging

For precision aluminum base tubes and their surface requirements, layered separation, surface protection, end protection, moisture protection, and impact-resistant packaging can be used to reduce scratches, contamination, impact damage, and end deformation during transport and handling.

Henan Chalco Aluminum can support samples, small-batch validation, and volume production, with continuous supply arranged according to fixed models, purchase quantities, and delivery schedules.
