Mechanical Design Division

Precision 3D
for the parts that
run the real world.

CATIA V5 mechanical design of plastic components.

Automotive —bumpers, door panels, pillars, and interior assemblies — with full draft, thickness, interference and sink-mark analyses to ensure every part is ready.

Manufacturing —3D design and modelling of plastic parts for consumer and industrial products — bottles, chairs, enclosures, custom components and more — with focused thickness and design analytics tailored to each part's requirements.

Every project is delivered as exported parts and ISO-compliant 2D drawings.

What we do

A focused plastic-parts engineering practice — built into SSC's DNA.

SSC 3D is the mechanical-design arm of Secure Shield Consulting. We lead 3D development and component design in CATIA V5, deliver technical solutions for complex DSM systems, and produce the same design-review analyses tier-one automotive plastics suppliers run before any mold is cut.

Our deliverables are tooling-ready: a complete bill of parts, a draft and thickness audit, every clip and fixation engineered, the assembly checked under interference, and 2D drawings that hold up to ISO scrutiny.

Plastic Parts — 3D Development

End-to-end design of injection-molded plastic components in CATIA V5/V6 — parts, surfaces, hybrid bodies, and full assemblies.

Tooling & Manufacturability

Precise tooling geometries, draft / thickness / sink-mark studies, and feasibility analyses so the part is mold-ready from the start.

Technical Analyses

Client-ready design-review packs covering exploded views, interference, clip / fixation, and assembly cuts — used for OEM project gates.

ISO 2D Drawings

Production-ready 2D drawings in strict ISO compliance — dimensions, GD&T, sections, tolerances — ready for tooling and supplier hand-off.

Services

Plastic components engineering, end-to-end.

Plastic parts are our core specialty. We take them from concept through tooling analysis to ISO-compliant production files — across two well-defined tracks.

Exterior & interior plastic components

Tier-one supplier workflow — production-grade geometry, manufacturability, and validation handled together.

BumpersDoor panelsA-pillarsInterior & exterior trim
  • Lead the 3D design and mechanical development of plastic components using CATIA V5/V6.
  • Develop precise tooling geometries and perform in-depth manufacturability analyses to ensure every part meets production and quality standards.
  • Coordinate technical validation with multidisciplinary teams and international suppliers, supported by detailed reports and full compliance with automotive engineering norms.

Manufacturing & consumer plastics

Plastic parts for industrial & consumer products

From the first concept sketch to production-ready files — with the analytics each part actually needs.

BottlesChairsEnclosuresCustom components
  • Design and engineer plastic parts for a wide range of products — delivering accurate 3D models tailored to your needs.
  • Perform injection-molding feasibility studies and tooling analysis to ensure your parts are optimized for manufacturing from day one.
  • Handle the full design process from concept to production-ready files, with clear technical documentation at every step.

Our Process

A six-stage CATIA V5 design review.

The same pipeline we ran across the Door Cover, Wheel Cover and Wheel Spoiler programs — adapted to each part, never skipped.

Stage 01 / 06

Exploded View

We deliver a clear exploded view that names every component, its quantity, and how it relates to the assembly — the visual spine of the entire review.

Per-part nomenclature & quantity callouts

Hierarchy: trim, sub-trim, fasteners

Used by every downstream stage as the reference

Case Studies

Three real OEM design reviews.

Confidential client work — anonymized programs, real CATIA deliverables. Each was run through the same six-stage pipeline.

Tech & Standards

The workflow behind every release.

Not just CATIA — a discipline. Standards, naming, exports and quality checks are baked into the process so the file you receive is the one your tooling can use.

Native

CATIA V5

Authoring environment for parts, surfaces and assemblies. We work in CATIA V5 from the first sketch to the released drawing.

ISO Drafting

Detailed 2D drawings produced in strict compliance with ISO drafting standards — dimensions, GD&T, sections, tolerance frames.

Interchange

Every part is exported into the formats your downstream tools speak — no one is locked out of the file.

Process discipline

Every release re-exports all four formats. Naming, units and origin are normalized — no surprises when files reach your CAM, CAE or 3D-print pipeline.
