Set Top Box Plastic Main Board Support Mould and Moulding Service | Renovator Appliances Ltd

Product Overview

Set Top Box Plastic Main Board Support Mould and Moulding Service is designed for manufacturing customized plastic support components used to position, support, and secure the main PCB or motherboard inside set top boxes, DTH receivers, cable TV receivers, IPTV devices, and other compact electronic equipment.

The main board support can be designed according to the PCB dimensions, mounting-hole locations, component clearances, enclosure geometry, and required fixing arrangement. It helps maintain the intended position of the main board within the enclosure and can incorporate mounting bosses, locating pins, screw posts, clips, slots, ribs, standoffs, and other positioning features.

Precision injection moulding supports accurate PCB mounting locations, consistent standoff heights, controlled clearances, and repeatable assembly. The component can be customized according to the OEM PCB and enclosure design.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The main board support is developed according to the PCB dimensions, mounting-hole locations, board thickness, component height, enclosure geometry, and required clearance. Connector positions, cable routing, fixing arrangements, and assembly sequence are also considered. CAD drawings, 3D models, PCB data, physical samples, or technical specifications can be used for development.

2. Plastic Mould Design

The injection mould is designed according to the support geometry, mounting bosses, standoffs, locating pins, screw posts, clips, snap-fits, ribs, slots, and other functional features. Gate location, parting line, cooling channels, venting, and ejection arrangements are considered for reliable moulding.

3. Mould Manufacturing

The mould can be manufactured using suitable mould steel such as P20 Steel, H13 Steel, or S136 Steel, depending on production quantity, selected plastic grade, dimensional requirements, surface finish, and expected mould life. Precision machining, EDM where required, fitting, polishing, and mould assembly are carried out according to the approved design.

4. Injection Moulding

The selected plastic material is heated and injected into the mould cavity under controlled processing conditions. Injection pressure, material temperature, cooling time, and cycle parameters are controlled according to the selected material and main board support geometry.

5. Finishing & Assembly Preparation

After moulding, gates and excess material are removed where applicable. The supports are checked for flash, short shots, sink marks, warpage, deformation, sharp edges, and other moulding defects. The parts are then prepared for PCB and enclosure assembly.

6. Quality Inspection

Finished main board supports are inspected for dimensions, mounting-hole alignment, standoff height, PCB clearance, enclosure fitment, retention features, and assembly compatibility.

Raw Materials

Material selection should consider PCB weight, mounting load, dimensional stability, operating temperature, vibration, electrical environment, assembly requirements, and the specific enclosure design.

Quality Control

• Raw Material Inspection: Plastic grade, colour, and incoming material condition are checked.

• Mould Inspection: Cavity, core, inserts, parting surfaces, cooling system, and ejection arrangement are inspected.

• Dimensional Inspection: Overall dimensions, wall thickness, boss dimensions, and critical features are measured.

• Mounting Alignment Inspection: Mounting bosses, holes, and locating pins are checked against the approved PCB layout.

• Standoff Height Inspection: PCB separation and support height are checked according to the specified design.

• PCB Fitment Inspection: The support is checked with the intended main board for proper positioning and clearance.

• Enclosure Fitment Inspection: Compatibility with the set top box enclosure and mounting locations is verified.

• Retention Inspection: Clips, snap-fits, tabs, slots, and other retention features are checked.

• Surface Inspection: Flash, sink marks, short shots, warpage, scratches, and other moulding defects are inspected.

• Assembly Inspection: PCB and enclosure assembly compatibility is checked.

• Packaging Inspection: Finished components are packed to minimize deformation, scratches, dust, and handling damage.
