At Cactus River, we understand the significance of innovation in offering a competitive edge and customizing existing products within minimized time-frames. We provide advanced mechanical engineering design services and solutions to companies in various sectors. Our mechanical engineering services facilitate complex product and mechanical design development as well as reduce the time to market the product. We are indeed a one-stop solutions provider for our clients throughout the product development lifecycle, ranging from conceptual design to manufacturing.

CAD Modeling / Detail Design

  • Mechanical CAD design of chassis frame, support structures to mount various sub systems like motion and control systems, EMDs, electronics, robots, custom machine enclosures, stationary and moving parts, etc.
  • CAD modeling of machined parts, sheet metal, cast parts, moulded parts, sheet metal parts, weldment, etc. in line with DFM principles, configuration management, etc.
  • Assembly modeling with constraining DOF, assembly simulation, creation of exploded and sectional views, configuration management, manage spatial constraints, etc.
  • Creation manufacturing drawings with information of BOM, Engineering instructions, orthographic views, dimensions, tolerances, annotations, revision history, drawing templates, etc.

BOM Management

NPI Phase Significant design changes happen during the new product development stage as the design starts evolving
Sustenance Phase Marginal changes happen during sustenance that could be of redundancy or customization
  • Change is expected during the product life cycle and it is important that the EBoM and MBoM are synchronized
  • BoM synchronization issues may lead to variance in engineering requirement vs. manufactured, supplier cost variance, stack incorrect inventory and costing huge for the company
  • Timely synchronization of EBoM and MBoM helps in bringing an Engineering feedback loop to Product Development

Engineering Analysis

  • Static and dynamic analysis to study stress-strain analysis of the machine frame subjected to the different types of loading (static, dynamic, vibrations, shock, etc.)
  • Static analysis to study the stress and deformation of machine structure while lifting and transportation operation
  • Seismic dynamic analysis of machinery systems, their supports and connections subjected to seismic excitation and shock
  • Microfluidic simulations for immersion lithography using CFD- focused multiphysics simulation

Concept Design

  • Develop multiple concepts of mounting sub-systems within the given spatial space and optimize the system
  • Analyze mechanical sub-systems & components, performing mechanical engineering design and calculations
  • Analyze potential failure modes, FMEA, study stress, strain, force, deflection of subsystem based on boundary conditions using FEA tools
  • Study Tolerance stack up analysis and mitigate the potential assembly variations in as produced conditions
  • Prepare technical reports and presentations for engineering approval. Engineering review toll gates – [PDR, DDR, CDR]

Engineering Change Management

  • Design changes are expected during NPI and sustenance phase, which could lead to design changes due performance, quality issues, producibility, assembly build issues, customization, customer requirements etc. which shall follow engineering change management process
  • Study the existing design problem, part redesign with solution, develop concepts & evaluation, detail design, design review by customer and ECO release

Model Based Definition

  • Embed product manufacturing information (PMI) directly in the 3D models, creating a single, reliable source of information and evade manual creation of dimensions
  • Product manufacturing information (PMI) defines a product and helps to follow a model-centricapproach and evade document-centricapproach that could be tampered
  • MBD is a 3D product definition platform with product manufacturing information, which is being directly consumed by downstream activities like manufacturing, production, quality, and supply-chain.
  • ASME Y14.41 “Digital Product Definition Data Practices” builds on the drawing-based standard ASME Y14.5 “Digital Product Definition” that includes geometric dimensioning and tolerancing
