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

Product Overview

Set Top Box Plastic PCB Support Mould and Moulding Service is designed for manufacturing customized plastic support components used to position, support, and secure printed circuit boards (PCBs) inside set top boxes, DTH receivers, cable TV receivers, IPTV devices, smart TV boxes, and other compact electronic equipment.

The PCB support helps maintain the required position and separation of the PCB from the enclosure base or other internal components. It can be designed according to PCB dimensions, board thickness, mounting-hole locations, component clearances, enclosure geometry, and assembly requirements.

The component can incorporate standoffs, locating pins, mounting bosses, screw posts, clips, snap-fits, slots, ribs, and other positioning or retention features. Precision injection moulding supports consistent dimensions, accurate PCB alignment, controlled standoff heights, and repeatable assembly.

Industrial Applications

Manufacturing Process

1. Product Design & Development

The PCB support is developed according to the PCB dimensions, board thickness, mounting-hole locations, component height, required clearance, enclosure geometry, and fixing arrangement. Connector locations, cable routing, and assembly sequence are also considered during development.

2. Plastic Mould Design

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

6. Quality Inspection

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

Raw Materials

Material selection should consider PCB weight, mounting loads, dimensional stability, operating temperature, vibration, electrical environment, assembly requirements, and 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: PCB mounting points, bosses, holes, and locating pins are checked against the approved design.

• Standoff Height Inspection: The required PCB separation from the enclosure is verified.

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

• Retention Inspection: Clips, snap-fits, tabs, and other retaining features are checked for proper engagement.

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

• 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.
