Sheet Metal Prototyping

Prototek Manufacturing began in 1987, as a family owned and operated business as a supplier of quick turn precision sheetmetal and machined products for the prototype markets. Today we are still a family owned and operated business and have recently launched into rapid prototyping of precision machining production as well. Our quality and turn times continue to be among the best in the industry. Serving industries such as robotics, semi-conductor, telecommunications, military, pharmaceutical, medical, computer technologies and aeronautics, Prototek Manufacturing now has machining, plating, painting, powder coating, silk screening and assembly capabilities all under the same roof to help save our customers time and money on their finished parts requirements.

Prototek Manufacturing multi-station punch press and 4000 watt laser run 24/7 which means faster turn times for our customers. Our highly qualified staff of employees take measures to ensure parts flow through our manufacturing process quickly and efficiently. Each operation goes through an in-process inspection to ensure the highest level of quality.

Mazak Nexus Allows Prototek’s Customers to Get Better Parts Faster

With the crashing economy, Prototek inevitably picked up many new customers from other sheet metal production shops. It reached the point where their Pulsar laser and Vipros Queen turret were running 90% of the day, every day! This being a great side effect of a poor economy, the new problem was simply not being able to handle the workload.

Prototek has continually added bigger, faster, and more accurate milling and processing machines to their arsenal over the years, trying out new technologies to find what fits them best. Earlier this year was seven new Hurco milling machines and the most recent addition is the VC Nexus 410A from Mazak Corp. (Florence, KY). Materials the company commonly works with include ABS resins, all stainless steels, and all non-ferrous materials including Kovar, Invar, tungsten, and titanium. Turning projects are held to tolerances of plus or minus 0.0001 in., milling to plus or minus 0.00025 in.

Recently faced with an 8% across-the-board price cut demand from a major customer, the company turned to its newest acquisition, its VC Nexus 410A from Mazak. “It’s not always the job, it’s how fast you can get it on and off the machine that often makes the difference,” Isabelle explains. “The faster we push our Nexus, the better it cuts.” The Nexus 410A features a powerful 25Hp 12,000 rpm AC spindle motor that increases torque in the lower range and enhances performance in the high range. Spindle speed in the Nexus represents a 20% increase over previous models and horsepower is a 25% increase. The chip-to-chip tool-change time is 2.7 seconds.
“We absolutely had to cut time on existing jobs, and tool-change time is critical,” Isabelle
Explains. “When we began dealing with Mazak, it was clear they took machine construction and specifications seriously.” Programming capability, along with well-laid-out electrical components also aid profitability. A program running on a Haas mini mill was loaded onto High Tech Turning’s Nexus 410A, and without any changes the Nexus cut 45 seconds out of a four-minute cycle time, a nearly 20% reduction. Other medical parts run on the Nexus machine achieved nearly 50% reduction in cycle time, and an ABS component for a cough-assist machine run on the Nexus
could not be run on High-Tech’s other machining centers. Precision linear guide ways are used on all Nexus 410A axes for maximum accuracy and rigidity. Rapid traverse rates of 1417 inches per minute are a result, as well as positioning accuracy of plus or minus 0.0002 in. High-gain digital AC servo motors are coupled directly to the ballscrews, eliminating the need for belts and gears that can otherwise negatively affect machine accuracy. The Nexus design is environmentally friendly as well. An automatic save-energy mode shuts the machine down when not in use, which can cut electric power consumption up to 20%. The Nexus grease lubrication system reduces waste oil 57%, and the absence of tramp oils from the linear guide lubrication system extends coolant service life. In addition, all solenoids, valves, and fluid level gauges are mounted on a single panel, making a visual status check quick and easy.
“We always have to look at how we can cut cycle time out of a part,” Isabelle states. “If you can’t get the job out of the shop quickly, you don’t get the job. With the Nexus, we feel we have the technology to address our customers’ concerns and still maintain a profit.”
