laser automation from WLSC In this video Worldwide Laser Service Corporation [WLSC] demonstrates laser automation and laser system integration with an LP8100 100w Co2 laser system to laser cut acrylic [laser cut plastic] in a laser degate operation where the automated laser system is used to cleanly and quickly remove the part from the injection mold tree.

 

In these applications the use of laser automation provides some significant benefits to the production facility as follows:

  • Blades and saws are eliminated so that laser automation completely eliminates all physical contact with the product, there are no knifes, blades, or saws to wear out and get dull so all scrap and waste of parts caused by contact to the part of dull or damaged cutting instruments is complete eliminated
  • Laser automation from WLSC the LP8000 and LP9000 series are galvo based beam delivery system and come with standard f-theta focus optics providing standard laser cutting or laser marking fields from 50.8mm x 50.8 mm [2 inches square] up to 450mm x 450mm [18 inches square] meaning the laser cut from an automated laser system can hit any target within the defined cutting or marking field without moving either the laser or the product being laser cut or laser marked.
  • In many of these types of laser automation for degate operations one of two methods of laser cutting plastic is utilized as follows: [WLSC can design, build, and install with fully after installation warranty and technical support automated laser systems for cutting and laser system integration for marking products which utilized and incorporate all or some of the elements mentioned below]
    • 1. A robot presents the parts to the laser automation, the robot or articulated arm [also vacuum pick and place] picks up the part from the injection mold and presents the part under the laser for cutting, the laser automation accepts a fire signal from the robot [articulated arm or vacuum pick and place] and the laser fires a pre-selected cutting pattern [or marking pattern depending on the application] on the ‘gate’ or connector of the part to the injection mold tree. If there are multiple gates the laser automation can laser cut all the plastic gates in one pass provided the area of the gates to be cut is within the cutting working area of the lasers f-theta lens.
    • 2. The laser automation is placed on a stand or frame with a fixture located below the part to be laser cut is placed into the fixture [by an operator, by a robot, by an articulated arm, by vacuum pick n place – for example, obviously there are other ways to accomplish this task however these are most common we see in industry]
    • The point is that by either of these methods or some other design as long as the part for laser degate, laser cutting, or laser marking, is consistently placed in the same location and the laser fired there is 100% repeatability of the laser cut and the quality of the laser degate operation.
  • Generally speaking plastic parts laser automation and laser cutting come in either acrylic or polycarbonate, laser automaton and laser cutting systems work extremely well for cutting acrylic which has a loosely packed molecule structure integrated laser cutting system produce excellent results when laser automation and laser cutting is presented with acrylic with smooth polished clear non damaged surfaces which is perfect for displays, aquariums or tanks, security screens, decorative displays, automotive parts, electronic components, cellular phones and aerospace parts.
  • Polycarbonate and laser automation or laser cutting systems however are not so well matched, the molecule structure of Polycarbonate is very dense and tightly packed and when hit with laser light excessive amounts of heat are produced which brown or yellows the plastic being laser cut or is some way discolors the product, if the part is used in automotive application for example and is chrome finished, power coated, or in some other fashion covered in an exterior finish then the discoloration cased on the polycarbonate by the laser cutting system will not affect or interfere with the end use of the product and the advantages of laser automation and laser cutting can be useful, however if the product is presented to the final use raw or unfinished in some way as is typically common of high end polished injected molded polycarbonate products then laser automation and laser cutting systems might not be the best alternative.The primary business of Worldwide Laser Service Corporation [WLSC] is to provide laser automation and fully integrated laser products to industry and to help eliminate or significantly reduce any production problems or issues your manufacturing facilities might be experiencing.

  • Founded in July of 1986 in Phoenix Arizona WLSC was originally focused on laser system repair, refurbishment, and repair or replacement of internal electronic components for T.E.A. [transversely excited atmospheric] Co2 lasers, which employed masks for laser etching parts primarily in the discrete electronics components industry [ I.E. T0220;s SOT23, etc.] and which were often coupled with reel to reel handlers and testers, after several years of operations and at the request of end users [customers] WLSC expanded in beam delivery systems and components to compliment laser marking systems such as the 920 and 930 laser mark series, expanding again after several more years WLSC designed and built the LP2000 series of spark gap and thryraton driven T.E.A Co2 lasers over the years installing and managing many hundreds of these systems, WLSC then stated moving in the field of designing, building and installing laser automation becoming the leading laser integrator for laser marking and laser cutting systems. Today WLSC provides laser automation which laser cut plastic, laser cut rubber, and provide fully laser system automation for WLSC customers WLSC specializes in laser automation using Co2, Fiber-YAG, and 355nm UV laser platforms,
