Industry applications

Different industries, distinctive parts

Explore plastic part families by their role in a system, from structural carriers and flow paths to housings and fastening components.

AI-generated application illustrations show representative part geometries, not customer project photographs.

Automotive cabin & body parts

Door panels, console carriers and sunroof supports bring multiple mounting points into one part. The mating assembly defines the geometry.

Integrated mountingRibs & bossesAssembly fit

Engineering focus

  • Define locating points and mating surfaces before assigning tolerances.
  • Review rib transitions, draft and gate locations around the main attachment features.
  • Include assembly loads and visible-surface requirements in the part brief.

Automotive air & cooling parts

Branched housings and long tank bodies connect flow paths to the rest of the vehicle. Ports, joints and mounting points each have a different role.

Port geometryJoint interfacesThermal exposure

Engineering focus

  • Specify the operating temperature, fluid exposure and pressure conditions.
  • Identify sealing interfaces and the intended joining method.
  • Review material choice and validation requirements for the actual application.

Automotive lighting & exterior

Light-transmitting covers and open grille patterns make surface quality part of the product experience. Appearance and attachment need to work together.

Surface finishMounting tabsExposure conditions

Engineering focus

  • Identify visible surfaces, texture direction and appearance criteria.
  • Define the optical role where relevant; transparency alone is not an optical specification.
  • Consider weathering, coating and attachment requirements for the intended location.

Home appliance components

Water channels, divided drawers and open baskets solve very different problems. The design starts with how water, cleaning agents and people interact with the part.

Flow pathsCompartment designHandling & cleaning

Engineering focus

  • Describe temperature cycles and contact with water or detergents.
  • Review drainage, handling points and access for cleaning.
  • Define how the molded components join the complete appliance assembly.

Electronics & handheld housings

A housing has to make room for the electronics and the person using them. Button openings, grip areas and connector positions shape the finished device.

Enclosure fitGrip interfacesConnector layout

Engineering focus

  • Share the board outline, connector positions and assembly sequence.
  • Define screw, snap-fit and two-material interfaces where required.
  • Specify any impact, ingress or electrical requirements; these are not implied by the pictured form.

Industrial adjustment & fastening

Knobs, thumb screws and adjustable sleeves make a system easier to set, hold and service. Metal interfaces and grip geometry do much of the work.

Threaded interfacesManual adjustmentService access

Engineering focus

  • Identify mating threads, engagement length and the direction of applied load.
  • Define grip clearance and the frequency of adjustment.
  • Review insert retention, assembly method and material exposure together.

Six application questions

You do not need every answer before contacting SRRP. These are the conditions our team will help make visible before tooling and approval decisions are locked.

01

What must the part do?

Protect, locate, support, fasten, carry or complete an interface.

02

What touches it?

Mating geometry, fasteners, fluids, surfaces and operators.

03

What acts on it?

Load, impact, vibration, wear, temperature and exposure.

04

How is it assembled?

Orientation, access, clips, inserts, routing and poka-yoke.

05

What defines approval?

Fit, appearance, critical dimensions and functional evidence.

06

How will it be supplied?

Demand rhythm, packing, labeling and replacement planning.
