Talha Javed Malik provides mechanical engineering services for manufacturing companies, engineering and hardware startups, product designers, automation teams, industrial equipment manufacturers, medical device developers and consumer product companies. Start with focused mechanical CAD services, DFM, simulation or engineering documentation, then combine disciplines into a controlled product development scope. These engineering design services can support one defined technical problem, overflow design capacity or a complete mechanical product development program. The work connects requirements, parametric CAD, design reviews, prototype development, manufacturing feedback and production release so each decision is recorded and each deliverable supports the next stage. Review mechanical engineering projects for applied examples or learn more about the mechanical design engineer responsible for the work.

Core engineering services

Engineering services organized around manufacturing decisions.

Start with the next product or manufacturing decision, then build only the engineering scope it requires.

Each service begins with the decision a customer needs to make: how the product should work, how it will be manufactured, what files suppliers need and what risks should be checked before money is committed to prototypes, machining, tooling or production.

Overview

Design for Manufacturing reviews for injection molded plastic parts, CNC machined components and sheet metal assemblies. DFM services examine geometry, tool access, wall thickness, draft, undercuts, bend relief, inside radii, standard stock, fastening, datum strategy, tolerance demand and assembly sequence before cost is committed.

Findings are translated into specific CAD revisions rather than delivered as a generic checklist. Supplier or vendor feedback can be reviewed against the functional requirements so cost-saving changes do not quietly compromise fit or performance.

The result is a clearer manufacturing process, fewer quotation questions, more reliable prototype builds and a more controlled release to tooling, machining or fabrication.

Finite Element Analysis Services

  • Structural and thermal FEA
  • Loads and constraints
  • Mesh quality review
  • Stress and temperature results
  • Design validation
EV battery pack enclosure with structural and thermal finite element analysis contour plots
Engineering evidence from the existing project portfolio
Overview

Structural and thermal finite element analysis for brackets, enclosures, actuators, frames and load-bearing mechanical assemblies. FEA begins with the engineering question: expected loads, constraints, contacts, materials, operating conditions and the failure mode that matters.

Geometry is simplified deliberately, mesh quality and sensitivity are reviewed, and results are interpreted against stress, displacement, temperature or factor-of-safety requirements. Assumptions and limitations are documented so a contour plot is not mistaken for design proof.

Analysis findings feed back into CAD changes, design validation, prototype testing and review decisions before expensive tooling, CNC machining or fabrication is authorized.

Deliverables
  • Structural FEA
  • Thermal analysis
  • Load-case definition
  • Boundary-condition review
  • Mesh convergence check
  • Stress and displacement results
  • Design recommendations
  • Technical report

Typical Applications

  • Load-bearing components
  • Equipment structures
  • Thermal enclosures
  • Design validation before tooling

Software Used

  • SolidWorks Simulation
  • ANSYS Mechanical
  • ANSYS Thermal

Manufacturing Outputs

  • Contour plots
  • Result tables
  • PDF engineering report
  • Revised validation CAD
Revision Process

Loads, restraints, contacts, materials and acceptance criteria are agreed before solving. Results are translated into specific design changes, then the revised model is checked against the same documented validation basis.

Common engineering workflows

Combine services around the decision the product needs next.

Each service has a focused scope for search and procurement clarity, but real product development usually combines several disciplines. The engagement can begin with one urgent deliverable, then expand only when the next engineering decision requires it. Requirements, assumptions, design reviews, supplier responses and approved revisions remain connected so manufacturing teams receive a coherent handoff rather than disconnected CAD files.

Concept to prototype

Product design, CAD modeling and prototype development.

Resolve the product architecture and prepare editable CAD for a focused first build.

Useful when a new product needs its mechanical architecture resolved before a first build. The workflow combines product design engineering, parametric CAD, internal packaging, mechanical assembly logic and early DFM review. Prototype files are prepared for the selected rapid prototyping or machining process, then fit, function and assembly findings are captured in a design review. The output is an editable model and a clear revision path, not a one-off prototype file that must be rebuilt before production.

Design validation

FEA, tolerance review and controlled engineering revisions.

Create evidence for critical design decisions before committing to tooling or production.

Useful when a team needs evidence before committing to tooling or production. The scope can combine finite element analysis, tolerance analysis, interface checks, material review and physical prototype findings. Loads, boundary conditions, acceptance criteria and uncertain inputs are documented before simulation begins. Results are translated into specific CAD changes, then checked through a repeatable review and revision process. The manufacturing outcome is a better-supported design decision and a clear record of what was validated, what changed and what still requires physical testing.
