Precision Repairs Under Pressure

Despite its impressive capabilities and global reach, Intralox faced a significant challenge in its tool room operations. The company's diverse product line means that its molds come in all shapes and sizes, often with intricate designs and hard-to-reach areas. When these molds need repair, the stakes are high. Having the right mold repair equipment is critical, including the presses to run the molds once they are repaired.

The headquarters facility in New Orleans has 136 molding machines and its Hammond, Louisiana facility houses 99 molding machines for a total of 235 presses, ranging from 250 to 650 tons. “50% of the molds we work on run in the New Orleans facility with another 45% running in the Hammond plant about 50 miles away, and 5% to outside vendors that run our molds,” Chris Howard, Intralox Mold Shop Supervisor says.

"Emergency repairs are our top priority," explains Howard. These issues could impact customer orders or even pose safety risks. We need to address repairs immediately, making our repair process, equipment and molding capabilities essential."

However, the main challenge isn't just about speed. Precision is equally crucial. Many repairs involve extremely small, precise welds on complicated finished surfaces. The tool room team often finds itself grappling with repairs in hard-to-reach places, pushing the limits of their equipment and skills.

Adding to the complexity, the tool room frequently has to juggle multiple high-priority requests simultaneously. With only three dedicated moldmakers in their unscheduled repair cell, efficient workflow management is critical.

The integration of the Alpha Laser ALFlak into Intralox's tool room operations has not only solved their immediate challenges but also positioned them for future growth and innovation.

Their process involves sending a damaged mold to the "DIN CELL" (Do It Now) for evaluation. Meanwhile, the mold technician completes a repair request form with all necessary information to help prioritize each job. This form includes details about the part the mold produces, a brief description of the problem, photographs of the damage, and a sample part highlighting the affected area.

Upon the mold's arrival, the team inspects it and estimates the repair duration based on the damage. If the mold is not repairable, they submit a mold design request for engineering support. Engineering then assigns a designer who orders the necessary materials, including steel, prints and step files, along with all other items required to fabricate a new replacement part. Either Intralox manufactures this part or an outside vendor is contracted for the job.

To complement their refined repair process, they now sought a technology solution to help them tackle these challenging repairs quickly and accurately.

Laser Welding to the Rescue

Intralox found their answer in the Alpha Laser ALFlak laser welding system. This advanced piece of equipment proved to be the game-changer they were looking for.

The Alpha Laser ALFlak is a high-precision laser welding system designed for versatility and accuracy. Its standout feature is a flexible laser arm that can project a great distance, enabling it to reach welding positions even in deep or complex molds effortlessly.

"The ALFlak's flexibility is truly remarkable," says Michael Barsanti, Alpha Laser Sales Manager USA and Canada. "Its turn-tilt optic can pitch from 0 to 40° and swivel a full 360°. This means operators can pinpoint the exact spot to weld, even in the most challenging geometries."

It also features a precision joystick and a microscope setup that enables incredibly fine control. "With the micro settings, we can perform welds using wire as thin as 0.003 inches," Barsanti explains. “This level of precision is crucial for repairing intricate mold surfaces without distortion.”

The system's power can also be adjusted on the fly, thanks to a foot pedal that enables operators to change laser parameters without taking their eyes off the microscope. This feature significantly enhances efficiency and accuracy during the welding process.

Intralox integrated the Alpha Laser ALFlak into their unscheduled repair cell, which they had set up seven years prior. This cell is equipped to handle almost any type of repair from start to finish, minimizing downtime and maximizing efficiency.

To make the most of this new technology, Intralox implemented a cross-training program for all three of their moldmakers. “We made it a priority for everyone to learn how to properly set up and run every piece of equipment in the tool room, including the ALFlak,” Howard says. “This versatility enables us to respond quickly to any repair need that comes our way.”
