Where is XKY Framing located?

XKY Framing is based at 77 Gexian Road, Yiwu City, Zhejiang Province, China — in the heart of the world's manufacturing hub. We supply framing machinery to customers globally.

What machines does XKY Framing manufacture?

XKY manufactures four main product categories: (1) Auto Underpinners — including the NN300 fully automatic quad-corner system (1,000+ frames/hour) and the NN400/NN500/NN600/NN700 pneumatic and CNC underpinners for joining 45° and 90° miter joints using V-nails. (2) Auto Cutting — including the NC600 industrial high-capacity stack saw and NC500 fully automatic stack cutting saw for double-miter cutting of MDF and wrapped profiles. (3) Frame Cutting — including the CT300 dust-free precision miter saw and CT400 pneumatic aluminium saw. (4) V-Nail Fasteners — compatible with all standard underpinner brands, available in soft, general-purpose, and hardwood grades from 7mm to 15mm.

How fast is the XKY NN300 automatic underpinner?

The XKY NN300 (SL-NN300) Fully Automatic Quad-Corner Underpinner joins all four corners of a frame simultaneously with a cycle time of 2–3 seconds, achieving over 1,000 joined frames per hour — up to 400% faster than manual operation. It is ideal for high-volume picture frame, mirror, and cabinet door production.

What is the difference between the NC500 and NC600 cutting saws?

The NC500 is a fully automatic stack cutting saw with a proprietary mold-based clamping system, best for complex or irregular moulding profiles up to 21.5" wide. The NC600 Industrial High-Capacity Stack Saw adds a 100mm (4") wide cutting range, anti-chip Three-Cut Mode, and zero-waste mirror-cut mode, boosting efficiency by 300–500% over manual saws. The NC600 is the flagship choice for large-scale laminated MDF and wrapped gesso frame factories.

Yes. XKY provides a comprehensive service package: remote technical diagnostics via WhatsApp, WeChat, or Teams; full HD video tutorial libraries; on-site installation and operator training; a preventative maintenance program; 24-hour urgent support; and express spare parts dispatch (DHL/FedEx/UPS) from our Yiwu warehouse. Genuine spare parts are also available through xkyframing.com.

The Gold Thick Sheet Corner Protector 20mm – model 1003# – is a precision-engineered metal corner protector by XKY Framing, designed for books, albums, frames, journals, and stationery. If you need a reliable gold thick sheet corner protector 20mm, this is the definitive choice in craftsmanship and consistency.

[H2] Why Choose the 1003# Gold Thick Sheet Corner Protector?
The 1003# Yellow Gold Thick Sheet Corner Protector (20x6mm) is the most durable small-format corner protector in the XKY Framing range, featuring a robust 0.5mm iron sheet that resists deformation under pressure. Despite its compact 20mm arm length, the thick construction ensures the corner cap maintains its shape even with heavy use on hardcover books, thick binders, and frequently handled items. The yellow gold finish provides a classic, premium appearance.

[H3] Applications & Use Cases
The Gold Thick Sheet Corner Protector 20mm suits commercial bookbinding, stationery gifting, frame-making, and artisan crafts. Its yellow gold finish is suitable for a wide range of cover materials and aesthetics.

[H3] Installation
Slide onto the corner, confirm the 6mm channel fits your board, then secure with craft adhesive or brads.

[H3] FAQ
Q: Why is the 0.5mm iron sheet significant for a 20mm corner protector?
A: Thicker sheet metal on smaller protectors prevents the arms from bending open when the corner is bumped or dropped, which is a common failure mode in thinner small-format protectors.

Q: How does Q12 compare to Q10 (1083# Gold 20x7mm)?
A: Q12 (1003#) has a shorter inner height (6mm vs 7mm) but a thicker iron sheet (0.5mm vs 0.3mm), making Q12 better for items where durability is the priority and Q10 better for thicker-board items.

Q: Is Q12 suitable for hardcover textbooks?
A: Yes. The 0.5mm sheet and 6mm inner channel are well-suited for hardcover textbooks and academic notebooks with standard board thickness covers.
