What Makes Kval the Industry Leader in Interior, Exterior, and Commercial Door Machinery?
Long-Lasting, High-Quality Machinery
We own every step of our machinery manufacturing process—from machining precision parts and welding the frames to electrical wiring, PLC setup, software development, and final application of our high-quality signature green frame coating—all at our production HQ in Petaluma, CA.
We start with the fundamentals: our machine frames are heavy-duty and specifically engineered to limit vibration and flexing—improving product output quality and increasing the life of the machine.
Our solid supports and clamps prevent unwanted material movement and flexure during operation, ensuring the most accurate and precise machining possible.
We prioritize high-quality components: from rack and pinion, ball screw, and belt components, to precision and long-lasting bearings.
The motors and drives we use are sized to handle the heaviest load conditions and to provide reliable and consistent quality machining.
Cutting Edge Technology
We incorporate dual CNC routers (right-hand and left-hand) for machining hinges and other open hardware, which guarantees the highest quality cuts and eliminates chip-out.
CNC-controlled hardware for the most precise and clean squared hinges and faceplates in the industry.
Our commercial and CNC prehung machines measure the door with encoders and automatically adjust hardware and software configuration to accommodate user-provided hinge and door specifications.
Our patented 6-Shooter and 8-Shooter technology provide the most reliable hinge application in the industry.
Our quick dump screw change system and newly patented RTSH rotary turret screw change system are the fastest and most reliable way to change screw colors.
Our intuitive and patented KvalCAM® machine-controlled software gives customers complete control and the creation of hardware templates and door files into the hands of our customers, all without having to write a single line of G-Code. KvalCAM can run offline, or be synced with other machines referencing a centralized database—and provides in-depth diagnostics to help operators troubleshoot issues without requiring third-party support.
Superior Safety Standards
All motorized equipment is fenced in with interlocked gates.
Feeders and moving heads have safety light curtains and/or safety laser systems. The machines will automatically E-Stop if an object enters designated safety zones while the machine is running.
All tooling spindle motors have drive controls to prevent free-spinning after each machine cycle.
We prioritize high-quality components: from rack and pinion, ball screw, and belt components, to precision and long-lasting bearings.
Dual hand controls are used in areas with pneumatic clamping and/or staple guns.
