1. Product Overview
This custom ABS mounting bracket adopts professional 2+1+1 multi-cavity injection molding structure matched with submarine gate (tunnel gate) and large sprue feeding system, specially engineered for mass production of high-precision plastic mounting brackets. Optimized for stable dimension control, automatic demolding, and smooth plastic flow, this injection molding solution effectively solves common production pain points such as insufficient filling, uneven stress, gate mark blemishes, and low output of traditional bracket molds.
Manufactured with high-quality ABS raw materials and precision mold processing technology, the finished mounting brackets feature excellent structural rigidity, stable physical properties, flawless surface finish, and consistent dimensional tolerance. Widely applicable for fixed mounting, supporting, and connecting parts in electronics, home appliances, automotive interiors, industrial equipment, and smart hardware industries, it is a cost-effective and high-efficiency precision injection molding solution for medium-to-large batch customized plastic bracket production.
2. Core Structural & Process Advantages
2.1 2+1+1 Reasonable Cavity Layout – Balanced Production & Cost Saving
The exclusive 2+1+1 cavity distribution design realizes balanced mold force and uniform melt filling in each cavity. Compared with conventional single-cavity or symmetrical multi-cavity molds, this structure flexibly adapts to customized production demands of different batch volumes. It ensures 100% consistent dimensional accuracy and surface quality of all finished parts, greatly improves single-machine production efficiency, and reduces unit mold opening and injection molding costs, perfectly balancing mass productivity and product qualification rate.
2.2 Submarine Gate (Tunnel Gate) – Flawless Surface & Automatic Separation
Equipped with hidden submarine gate feeding technology, the gate is set under the mold parting line without exposing marks on the product appearance surface. During ejection, the gate material and finished product are automatically sheared and separated, requiring no manual trimming or post-processing polishing. This eliminates secondary processing costs, improves production automation continuity, and delivers mirror-level smooth surface without scratches, sink marks or burrs, meeting high-standard appearance and assembly requirements of terminal products.
2.3 Large Sprue Design – Smooth Melt Filling & Stable Molding
The upgraded large-diameter sprue runner system optimizes ABS melt flow velocity and pressure transmission, thoroughly solving molding defects such as short shot, material shortage, flow marks, and insufficient filling of thick and thin alternating structures of mounting brackets. It ensures uniform melt filling of each cavity, stable mold pressure, and effectively reduces internal residual stress of products. The finished brackets feature excellent flatness and deformation resistance, laying a solid foundation for long-term stable dimension control.
2.4 High-Precision Dimension Control – Strict Tolerance Compliance
Adopting precision CNC machining, mirror EDM finishing and strict mold temperature control technology, the mold has high fitting accuracy and low deformation rate. Combined with mature ABS injection molding process parameters, the product dimensional tolerance is stably controlled within the industry standard range. The mounting hole position, assembly gap, and overall structural size of the bracket are highly consistent, ensuring perfect interchangeability of finished parts and smooth assembly of terminal equipment.
3. Material Performance (ABS Engineering Plastic)
This custom mounting bracket is made of high-performance ABS (Acrylonitrile Butadiene Styrene) engineering plastic, with comprehensive and excellent mechanical and processing properties:
High Structural Rigidity & Impact Resistance: Good hardness and toughness, not easy to break or deform under normal external force, stable supporting and fixing performance
Excellent Dimensional Stability: Low thermal expansion coefficient, not easy to shrink or deform in conventional temperature environments, suitable for long-term fixed installation scenarios
Superior Surface Performance: Smooth and delicate surface, good gloss, easy for surface treatments such as spraying, silk screening, and electroplating
Good Chemical & Weather Resistance: Resistant to daily dust, moisture, and weak chemical corrosion, stable performance for indoor and mild outdoor use
Mature Molding Process: Good melt fluidity, high molding yield, stable batch consistency, and low defective rate
