MINVEE Wholesale -30 Degree Negative Angle Aluminum Frame Cabinet Hinge (Slide-On / Non-Hydraulic)
Product Overview
This -30 Degree Aluminum Frame Hinge is specifically engineered for specialized inward-angled corner display cases, negative 30 Degree interior cabinet carcasses, glass-front aluminum wardrobes, and space-saving architectural millwork requiring reduced opening clearance. Designed for precise angled door mounting onto narrow 16 mm – 20 mm aluminum profile door frames, it replaces traditional circular cups with dedicated clamp bracket mounts.

Key Technical Features
- Specialized -30 Degree Negative Angle Geometry: Purpose-built for inward-folding or negative 30 Degree aluminum-frame joinery, allowing glass cabinet doors to swing open cleanly from interior side frames without colliding with adjacent carcass panels.
- Dedicated Aluminum Profile Clamp Mount: Precision clamp brackets tailored for narrow 16 – 20 mm aluminum extrusion door frames, securing aluminum profile edges tightly without cracking glass panels.
- High-Stability Fixed Slide-On Base: Traditional slide-on fixed base locks the hinge arm rigidly onto the mounting plate via a heavy-duty tracking screw, delivering long-term resistance against frame sagging under continuous leverage.
- Gunmetal Multi-Layer Electroplated Finish: Advanced electroplating process creates a rich, dark metallic aesthetic, perfectly matching black or dark grey anodized aluminum door profiles.
- Durable Mechanical Spring Action: Non-hydraulic dual-spring mechanism provides crisp, consistent closing force without any risk of fluid leaks over long service lives.
- Wholesale Bulk Packaging Integration: Tailored for volume B2B procurement with cost-optimized master carton packing configurations for international shipping.
Frequently Asked Questions (FAQ)
Q1: What aluminum door frame sizes are compatible with this negative 30-degree hinge?
A: This hinge is specifically designed for standard 16 mm to 20 mm thick aluminum profile frames. The mounting cup brackets screw directly into the internal channel of the aluminum profile.
Q2: What is the main application for a negative 30-degree (-30°) aluminum frame hinge?
A: Negative 30 Degree hinges are specified for inverted corner glass display cases, space-saving kitchen joinery, and angled alcove wardrobes where door panels open inward relative to the side carcass.
Q3: What is the practical advantage of a Non-Hydraulic hinge for volume B2B buyers?
A: Non-hydraulic hinges utilize simple, robust mechanical springs rather than fluid damper cylinders. This eliminates any risk of hydraulic oil leakage, keeps unit weight extremely low (59 g), and offers maximum price efficiency for budget-conscious project tenders.
