Pneumatic Anodizing Clamps with Pneumatic Control for Clamping and Holding of Aluminum Profiles in Anodizing Lines

Pneumatic Clamp for Aluminum Anodizing Line

Product Overview

In aluminum anodizing production, the clamp is not only responsible for holding profiles but also affects positioning stability, process consistency, and production efficiency. Traditional manual or mechanical clamps may experience unstable gripping, profile movement, and inconsistent positioning during long-term continuous operation.

The KRT-069 Pneumatic Clamp is designed for aluminum profile anodizing, electrophoresis, and surface treatment lines. Driven by pneumatic control, it provides fast opening and repeatable clamping performance. The clamp features a dual-side jaw structure with toothed anti-slip jaws. With a 37mm stationary opening, 87mm maximum opening, and 28.5mm toothed jaw length, it provides flexible and stable clamping for different aluminum profile applications.

Problem

Common Clamping Problems in Aluminum Anodizing Lines

1. Aluminum profiles may move during processing

During anodizing, aluminum profiles go through multiple processes including cleaning, oxidation, washing, and electrophoresis.

Vibration, liquid flow, and continuous movement can cause profile displacement if the clamp cannot provide stable gripping.

Possible results:

• Incorrect profile positioning
• Reduced process consistency
• Unstable production quality

2. Manual clamping cannot maintain repeatability

Manual clamps depend on operator force control, which may vary between workers.

This can result in:

• Different clamping force
• Lower production consistency
• Reduced automation efficiency

3. Different profile sizes require flexible clamping range

Aluminum profiles have various shapes and dimensions.

Insufficient jaw opening may cause:

• Poor gripping of smaller profiles
• Difficulty installing larger profiles
• Frequent fixture replacement

Cause

Why Traditional Clamps Cannot Fully Meet Automated Anodizing Requirements

1. Jaw design affects gripping stability

Flat jaws mainly rely on friction. In anodizing environments, liquid residue or surface conditions may reduce friction performance.

The RJ-Q33 uses a toothed jaw design to increase mechanical contact between the clamp and aluminum profile.

2. Manual operation limits repeatability

Anodizing lines require repeated clamping cycles every day.

Pneumatic actuation provides controlled and repeatable opening and closing operations.

3. Jaw opening determines application range

The opening range directly affects profile compatibility.

RJ-Q33 specifications:

• Stationary Opening: 37mm
• Maximum Opening: 87mm

Solution

RJ-Q33 Pneumatic Clamp Solution

1. Dual-side pneumatic clamping structure

The dual-side jaw design applies balanced gripping force from both sides.

Benefits:

• Improved profile positioning
• Better repeatability during continuous operation
• Suitable for automated production lines

2. 28.5mm toothed jaw design for stable gripping

The RJ-Q33 features a:

28.5mm toothed jaw length

The extended contact area improves gripping stability between the clamp and aluminum profile.

Suitable for:

• Aluminum anodizing racks
• Electrophoresis production lines
• Surface treatment systems

3. 87mm maximum opening for wider profile compatibility

RJ-Q33 specifications:

Maximum Opening:

87mm

Stationary Opening:

37mm

The wide opening range allows the clamp to handle different aluminum profile sizes and reduce fixture replacement frequency.

Application

Aluminum Surface Treatment Production Lines

The RJ-Q33 pneumatic clamp is suitable for:

• Aluminum Profile Anodizing Lines
• Electrophoresis Lines
• Surface Treatment Hanging Systems
• Aluminum Extrusion Plants

Typical process:

Profile Loading → Pneumatic Clamping → Anodizing Treatment → Washing → Electrophoresis → Unloading

Throughout the process, the clamp maintains stable positioning while supporting continuous production requirements.

How to Choose Pneumatic Clamp for Aluminum Anodizing Line

1. Select the correct jaw opening range

Consider:

• Profile width
• Profile cross-section
