rolling shutter slats roll forming machine

Rolling shutters utilize curved slat profiles that interlock to provide security and privacy. Roll forming is an ideal process to manufacture custom shutter slats from coiled steel. This guide covers slat roll former configurations, workings, customization, suppliers, and more.

Overview of rolling shutter slats roll forming machine

  • Roll form metal coils into various shutter slat profiles
  • Efficient continuous production with high speeds
  • Automated cutoff and punching integrated
  • Short lead times and lower costs
  • Widely used by rolling shutter manufacturers
  • Simple operation and quick changeovers between slat sizes

Roll formed shutter slats offer flexibility, speed and precision forming.

Types of rolling shutter slats roll forming machine

Major types of shutter slat roll formers include:

  • Standard roll formers – Basic models with manual adjustment
  • Servo motor roll formers – More advanced with precision control
  • All-electric roll formers – Eliminate hydraulics for quieter, cleaner operation
  • CNC roll formers – Fully automated for optimum efficiency

Higher volumes favor CNC and servo motor controlled roll formers.

Slat Roll Forming Process Overview

The rolling shutter slat roll forming process:

  • Coil Loading – Steel or aluminum coil loaded onto decoiler
  • Feeding – Coil fed into roll former infeed
  • Punching – Any slots or holes punched early in process
  • Forming – Slat formed gradually as it passes through roll stations
  • Cutoff – Formed slat cut from coil at specified length
  • Output – Extract finished shutter slats

The process allows high speed, automated production.

Roll Former Components

Key components of a shutter slat roll forming machine include:

  • Decoiler – Unwinds the raw material coil stock
  • Feeder – Feeds metal sheet into first roll station
  • Punch – Punches holes or slots in slat profile
  • Forming stations – Incrementally bend sheet into slat shape
  • Shear/Cutoff die – Cuts finished slat profiles from coil
  • Conveyor – Transports cut slats to collection
  • Controls – PLC automates production and provides diagnostics

Design and Customization

  • Roll stations and punches designed for exact slat configurations
  • Number of stations determines profile complexity
  • Quick change tooling allows fast profile changeovers
  • Adjustable for different slat widths and radii
  • Optional cambering for curved shutter profiles
  • Integration of powder coating possible

Proper design matches required slat dimensions and interlocks.

Installation and Operation

  • Install securely on level, rigid concrete per supplier instructions
  • Inspect machine thoroughly before initial operation
  • Gradually increase speeds during initial trial runs
  • Apply proper tension to coils before loading
  • Ensure safe operation and follow safety procedures
  • Perform routine maintenance for maximum longevity

Proper operation and care helps maximize productivity.

Maintenance Recommendations

  • Lubricate bearings, chains, gears and motors
  • Check roll alignment and adjust/shim as needed
  • Inspect drive belts and chains. Replace when worn.
  • Verify cutting blade condition and sharpen regularly
  • Confirm electrical, hydraulic and pneumatic connections are tight
  • Check PLC system for any faults
  • Clean machine to avoid dust/dirt buildup

Preventative maintenance reduces unplanned downtime.

How to Select a Roll Former Supplier

Key factors in choosing a shutter slat roll forming machine supplier:

  • Experience with rolling shutter and door systems
  • Capability to produce needed slat configurations
  • Offer appropriate levels of automation
  • Availability of quick change tooling for flexibility
  • Ability to modify designs as required
  • Reasonable delivery times on equipment
  • Responsive pre-sales engineering and service
  • Operator training and documentation provided
  • Positive reputation based on client reviews
  • Local representatives and parts availability

Thoroughly vet potential suppliers on these criteria before purchasing.

FAQ

What gauge metals can be roll formed into shutter slats?

Typical gauges range from 0.5 mm to 1.2 mm for steel and 0.8 mm to 2 mm for aluminum. Maximum capacities depend on equipment size.

What tolerances are held on roll formed slats?

Standard roll forming accuracy is +/- 0.5 mm. With CNC controlled electric servo roll formers, tolerances of +/- 0.25 mm are achievable.

How long does it take to do a roll change to a new slat profile?

Manual machines require 1-2 hours for a roll changeover. With advanced quick change systems, under 15 minutes is achievable.

Can PVC coating be added as a secondary process?

Yes, PVC coating can be optionally integrated by adding an unwind stand, pre-treatment, and extrusion crosshead for coating after roll forming.

Are powders or liquids required for roll forming?

No. Roll forming bends dry coil stock fed directly into the process. No liquids or lubricants are needed.

উপসংহার

Roll forming provides an efficient, high speed production method for rolling shutter slat manufacturers to meet demand. Integrating punching and cutting into the automated process minimizes secondary steps. With quick change tooling and precision electric or CNC roll formers, different interlocking profiles can be quickly produced on the same line. While needing moderate initial capital expenditure, over time roll forming results in lower overall costs and lead times compared to alternate methods. When properly leveraged, it can give manufacturers a competitive advantage in quality and price for rolling shutter components.
