Manufacturing

How we make this part

Process, material options and inspection for cnc machined aluminum cat flap for sliding screen doors.

The flap frame is machined from aluminum extrusion or plate, so the opening, hinge-pin bores and clip or screw holes are positioned consistently. Hinge pins are turned on CNC lathes to fit the frame bores for a smooth swing. Edges that pets brush against are radiused and deburred. Because this is an OEM product, we build from your drawing or help translate a sample or concept into a manufacturable design.

Aluminum alloy does not rust and keeps its shape in sun and humidity, which suits screen doors exposed to weather. Frames are commonly anodized or powder coated in black, white, silver or brand colors. Flaps are usually clear or tinted plastic, and magnets or brush seals can be included to reduce drafts and insects, depending on your specification and component sourcing.

Each frame is checked for opening size, hole positions and flatness so it seats evenly in the screen. Assembled flaps are cycled by hand to confirm free swing, and finishes are inspected for scratches. Products receive 100% quality inspection and are carton packed, with retail packaging possible on request. Typical buyers are pet-accessory brands, home-improvement retailers and screen-door makers.

FAQ

Frequently asked questions

Can the cat flap be made in my brand's size and color?

Yes. This is an OEM product, so frame size, opening, color and logo can be customized from your drawing or sample. Common frame finishes are black, white and silver anodize or powder coat. We send samples for approval before production.

Why choose an aluminum frame over plastic?

Aluminum frames stay rigid, do not crack in cold weather or warp in direct sun, and resist pets chewing or scratching the edges. They cost more than molded plastic, so they suit premium product lines or doors that see heavy use.
