Manufacturing

How we make this part

Process, material options and inspection for aluminum sliding screen dog door insert for small pets.

The insert frame holds the flap opening and clips or screws to the screen mesh. We machine the frame profile and fastener holes with CNC equipment so every unit fits the same way. Turned pins or machined hinge blocks give the flap a consistent pivot. All edges around the opening are rounded and deburred so pets and screen mesh are not damaged by sharp metal.

Aluminum alloy is light enough not to sag the screen yet strong enough to resist pushing and scratching by dogs. Anodizing protects it outdoors and comes in silver, black, bronze or brand colors; powder coating gives thicker, textured finishes. Flap material, closure magnets and weather seals are selected to suit your target market and price point.

Units are inspected 100% for frame dimensions, hole positions and finish quality, and a sample from each lot is assembled and swing-tested. Inserts are packed individually in cartons to prevent scratches, with retail boxes available on request. Typical buyers include pet-door brands, online pet retailers and screen manufacturers adding pet access options.

FAQ

Frequently asked questions

Will the insert fit any sliding screen door?

Screen frames vary, so fit depends on the frame depth and mounting method in your target market. We machine to your specification and can produce samples for testing on common screen types before production. Adjustable mounting details can also be designed in.

What flap size suits small dogs?

Flap size should match the shoulder width and height of the target breed with some clearance. Many small-dog flaps are designed for pets up to roughly toy and small breed sizes. We build to the opening you specify and can make several sizes in one order.
