Injection molds are the backbone of countless manufacturing operations. When they fail, production grinds to a halt, leading to costly delays and lost revenue. That’s why efficient, precise, and reliable mold repair is paramount. At Alpha Laser, we understand these critical needs, and our ALFlak laser welding system is engineered to put you back in production faster, with unparalleled accuracy. Designed for versatility and ease of use, it empowers mold makers to achieve previously unattainable levels of precision.

Key Features that Make the ALFlak Stand Out:

• 360° Swivel Head: This innovative feature allows for unparalleled access to complex geometries and hard-to-reach areas within the mold, minimizing the need for extensive mold disassembly.
• Intuitive Joystick Control: With a single toggle for X, Y, and Z-axis movement, the joystick provides precise, ergonomic control, allowing for smooth and accurate positioning of the weld spot.
• Foot Pedal Parameter Control: Keep your hands free for fine manipulation. All essential welding parameters are conveniently controlled via a robust foot pedal, streamlining your workflow and enhancing efficiency.
• Variety of Wattage Options: The Nd:YAG option comes in 200 or 300w power sources. The fiber laser comes in 300, 450, 600, 900 & 1200w power sources.

Real-World Precision: A Stainless Steel Mold Repair Example

Let’s illustrate the ALFlak’s capabilities with a common scenario: a design change on a stainless steel injection mold component.

The Need: A design modification required all sidewalls up to the parting line to be shifted inward by a precise 0.025 inches. This type of repair demands extreme accuracy to ensure the integrity and functionality of the final molded part.

The Result: A perfectly executed design change, with the sidewalls precisely shifted inward by 0.025 inches, ready for subsequent machining and finishing. The ALFlak’s precision ensured that the structural integrity and surface finish of the mold were maintained, leading to a high-quality, functional component.

Invest in Precision, Reduce Downtime

The Alpha Laser ALFlak system is an indispensable tool for any facility involved in injection molding. Its advanced features, coupled with its robust construction, make it the ideal solution for:

• Repairing wear and tear
• Correcting design flaws
• Adding or modifying features
• Salvaging expensive mold components

By investing in an ALFlak, you’re not just buying a laser welder; you’re investing in increased uptime, reduced costs, and the peace of mind that comes with knowing your molds are always in peak condition.

Summer’s here, and so is the heat! Is your Alpha Laser system ready?

Just like you wouldn’t want to run a marathon in a sauna, your laser doesn’t perform its best in extreme temperatures either. Overheating can lead to all sorts of headaches – from reduced performance to costly downtime. That’s where a Water Chiller comes in. Think of it as your laser’s personal air conditioner, a vital piece of equipment that keeps your system running smoothly by preventing it from getting too hot.

When is a Water Chiller a must-have for your laser welder?

• You’re Pushing Your System: Sometimes, project demands increase, and you might find yourself using your laser more than usual. All that extra work generates heat, and a chiller ensures your system can keep up without breaking a sweat.
• High-Power Jobs: Working with materials that need higher parameter settings? These operations naturally produce more heat. A chiller actively dissipates that extra warmth, letting you tackle intensive tasks confidently.
• No Perfect Climate Control? No Problem! Not every workspace is an ideal, climate-controlled environment. If your laser system is exposed to higher ambient temperatures, a Water Chiller provides the necessary internal cooling to counteract the external heat.
