FAQ — Hardware Solutions

Answer: Main types include butt hinges, concealed (European cup) hinges, pivot hinges, and spring hinges. Selection depends on door type, weight, frequency of use, and installation method. We recommend consulting our engineers for project-specific guidance.

Answer: Full overlay — door fully covers the side panel. Half overlay — door partially covers the side panel, used for two adjacent doors sharing one panel. Inset — door sits flush inside the cabinet frame. Choose based on your cabinet structure.

Answer: Main types include floor-mounted, wall-mounted, magnetic, and mechanical door stops. Materials include zinc alloy, stainless steel, and brass. Selection should consider installation location, door weight, and environment (indoor/outdoor/humid areas).

Answer: Concealed hinges offer 80kg–150kg load capacity with tiered options; a 20% safety margin is recommended. Standard doors need 2–3 hinges; heavy or extra-tall doors require 4+ hinges. Calculate based on door size and weight.

Answer: 304 stainless steel offers excellent corrosion resistance for humid environments like kitchens and bathrooms. Industry standard salt spray tests typically require 500+ hours. Coastal or outdoor projects require higher-grade materials.

Answer: Soft‑close hinges feature a built‑in damper that creates hydraulic resistance during the final stage of closure, allowing slow, silent closing without slamming. Damper quality and spring durability directly impact product lifespan.

Answer: Requires drilling a 35mm cup hole in the door panel. Tools needed: drill, 35mm hole saw, and screwdriver. We recommend using an installation template for accurate positioning. Verify hinge matches door frame and leaf before installation.

Answer: Most concealed hinges feature three adjustment screws: vertical (height), depth (door‑to‑cabinet distance), and horizontal (gap control). All three adjustments can be made with just a screwdriver — quick and precise.

Answer: Usually caused by lack of lubrication or excessive friction. Apply silicone spray or appropriate lubricant at friction points, or add shims to reduce friction. Regular cleaning and lubrication of moving parts is recommended.

Answer: Yes. shingStar offers one‑stop custom services including dimensions, materials (stainless steel / iron / brass / zinc alloy), surface finishes (zinc plating, chrome plating, nickel plating, powder coating), and brand logo imprinting.

Answer: Please provide: application scenario (door type, weight, environment), dimensions (length/width/thickness/hole diameter), material grade, surface finish requirements, and target market. Drawings or physical samples greatly accelerate the process.

Answer: Stock products have lower MOQ; custom products vary by process and order volume. Contact our sales team for specific quotations and lead times. We fully support sample delivery for client testing and validation.

Answer: shingStar complies with ISO 9001, ANSI/BHMA A156.1 (US), EN 1935 (Europe), and CE certification. Third‑party test reports are available upon request for your quality assurance.

Answer: Includes salt spray tests (500+ hours corrosion resistance), load validation, cycle testing (over 100,000 cycles), and CMM dimensional inspection. We recommend clients request physical samples to evaluate finish quality and craftsmanship.

Answer: Quality consistency ensured through CNC stamping centers, automated electroplating lines, dedicated R&D teams, and 3,000m²+ production floor. Advanced tooling ensures superior dimensional accuracy and faster prototyping.
