CO2 Laser Tube Factory Checks: What Buyers Should Ask Before Ordering

An effective way to ensure your tubes are correct before production is to agree a model and what checks are being done. When purchasing tubes you can ask the following:

1. Model

Ensure the model number is included on your quote/purchase order. Include the Rated Power, Dimensions and Electrical Specifications. If you're replacing a tube, ensure you include a clear picture of the tube label and machine power supply model.

This will ensure you don't get a tube of the wrong size or electrical spec. Ask the factory to confirm the model in writing.

2. Product Identification

Ask if there is a model number and batch/serial number on the tube label or packing slip. This will allow the receiving team to easily match up the tube to the correct carton, purchase order and service requests.

If you're ordering in a batch, agree what information you want on the cartons. Save a copy of the approved label. If you require a distributor barcode/label, ensure to know where it will be placed so it won't hide any product information.

3. Testing

Ask what tests are done on the model. It's a good idea to have a record of what model it is and what test was done. If they just say "testing" then you won't know what tests are being done. If they're testing the output using a power meter, ask if it can be tied back to a unit/batch.

Puri Laser state that they have quality control throughout the manufacturing process (Glass tubes, Gas fill etc) and state on their website that they test the tubes prior to dispatch. Ask what records are available for your model/order.

4. Machine Compatibility

Before production, provide the power supply model and what machine you're using the tubes on. Ask for the recommended current and any electrical requirements. If you're changing the power range, you shouldn't assume the power supply and wiring will work.

Provide the cooling system on the machine. Ask what the requirements are for the chosen model and ensure they match up with the machine manual. This will give clear guidance to the installer.

5. Packaging

Agree how you want the tubes packaged for protection. What information should be on the carton/crate? What pictures should be taken? If it's a long glass item, having a picture of how the tube is held in place and sealed on the outside carton will help both parties review any damage during transit.

Let the supplier know if there is any labelling required for the destination. By confirming this early, you'll avoid any delays to your order if the carton needs to be labelled differently.

6. Sample

If you're bringing in a new model or supplier, test a sample in the machine. Take a note of the label on the tube, power supply, cooling system, material and settings. Add this to your purchase order.

When the next batch comes in, check the model and documents match the approved sample. If the spec changes, amend the order prior to production.

Puri Laser have been manufacturing CO2 laser tubes since 2009. They have a range of products for engraving, cutting and industrial uses. To get a quote, provide them with the model/machine you want, power supply, cooling system, quantity and packaging requirements at destination. Ask them to confirm the model, what records they have available for inspection and packaging plan in writing.
