Custom Plastic Control Module Housing
This molded plastic housing is designed for electronic control modules, electrical assemblies and industrial control devices.
The enclosure shown is a fully customized structural component, with mounting feet, internal screw posts, reinforced walls, connector openings and positioning features integrated into a single molded part.
SWKS can manufacture similar housings based on customer CAD files, technical drawings or reference samples.
Typical Structure
The housing can be designed with different functional details such as:
PCB mounting posts
Internal partitions
Reinforcing ribs
Connector openings
Cable entry holes
Mounting ears
Screw fixing points
Snap-fit locations
Positioning tabs
Ventilation openings
These features can be molded directly into the part to reduce additional assembly work.
Available Materials
Material selection depends on the mechanical and electrical requirements of the project.
Common choices include:
ABS
Commonly used for electronic housings with good appearance and general mechanical performance.
PC/ABS
Suitable when improved impact resistance is required.
PA66
Used for stronger structural parts and mounting components.
PBT
Often selected for electrical and electronic applications.
PP
Available for lightweight and chemical-resistant designs.
Flame-retardant, glass-fiber-reinforced or customer-specified resin grades can also be evaluated.
Custom Details
The following items can be produced to customer specifications:
Dimensions
Housing length, width, height and wall thickness.
Internal Layout
PCB supports, screw bosses, ribs and positioning structures.
Openings
Connector windows, cable holes and mounting holes.
Surface
Fine texture, matte surface, smooth finish or specified mold texture.
Color

Insert Components
Brass inserts, nuts or metal sleeves can be added when required.
Production Method
The housing is produced by injection molding.
For a new project, the process normally includes:
Drawing confirmation → mold manufacturing → first samples → sample approval → production.
Both small trial quantities and repeat production projects can be evaluated according to part size and tooling requirements.
Inspection Requirements
Important dimensions can be controlled according to the customer drawing, especially:
Mounting hole locations
Connector opening dimensions
PCB post positions
Boss height
Wall thickness
Overall housing dimensions
Assembly fit
Visual inspection can also cover flash, deformation, sink marks, color and surface condition.
