Precision Tooling & Manufacturing Support Services

Tool & Die | Jigs & Fixtures | SPMs | CNC Programming | Rapid Prototyping

At NESTech, we empower modern manufacturing with intelligent tooling solutions. Backed by decades of engineering experience and trusted partnerships with global manufacturing leaders, we bring both design precision and production practicality to the table. From complex Tool & Die design to rapid prototyping and CNC programming, we enable clients to move faster, build smarter, and manufacture better.

Our Specialized Tool Design Services Include:

Tool & Die Design - Plastic & Pressure Die Casting

Our tool design begins from the digital model of the final component, carefully incorporating material shrinkage and manufacturing allowances. We use associative parametric modeling to ensure design changes in the part automatically update the tool design-ensuring agile response to late-stage modifications without compromising deadlines.

Our tooling designs include core and cavity blocks, inserts, lifters, sliders, and cooling channels, with standardized mold base integration (FUTABA, DME, HASCO, etc.). Whether you're working with injection molding or high-volume die casting, we ensure robust designs optimized for tool life, ease of maintenance, and production throughput.

Foundry Pattern Design & Casting Solutions

With deep roots in foundry operations, NESTech engineers design precision patterns tailored to your casting methods and materials. Our deliverables include design for:

  • Patterns in Wood, Aluminum, Cast Iron, and Gun Metal
  • Sand Casting, Shell Molding, and Match Plate Systems
  • Lost Wax Casting (Investment Casting)
  • Gravity, Low Pressure, and High-Pressure Die Casting
  • Resin-based prototypes for one-time tooling or testing

We support customers with end-to-end casting readiness-from optimizing part geometry to designing patterns that increase yield, reduce scrap, and enable better flow characteristics.

Jigs, Fixtures & Special Purpose Machines (SPMs)

Whether you're manufacturing automotive components, complex weld assemblies, or inspection tools-jigs and fixtures form the bedrock of repeatability and precision. Our team designs robust fixtures tailored for:

  • Automotive plastic parts like bumpers and grilles
  • High-accuracy welding and inspection fixtures
  • Duct trimming, assembly, and testing stations
  • Custom SPMs for part handling and automation

We also offer consultancy, manpower support, and technical assistance for fixture standardization, process integration, and equipment upgrades.

CNC Programming & NC Code Generation

Precision machining starts with optimized tool paths. Our experienced CAM programmers develop custom CNC strategies tailored for efficiency, finish, and part complexity. We provide:

  • 3-axis and 5-axis NC Programming
  • Machining Process Planning & Simulation
  • Toolpath Optimization for Minimum Cycle Time
  • Cutting Tool Selection & Surface Finish Analysis

From prototype parts to production volumes, our CNC services bridge the gap between design intent and real-world manufacturability.

Rapid Prototyping & Rapid Tooling

Accelerate design validation with physical prototypes and low-volume tooling. NESTech and its channel partners offer:

  • SLA, SLS, and LOM prototypes for form & fit analysis
  • Sintered metal parts for functional testing
  • ABS and high-resolution plastic parts
  • Rapid Tooling for plastic injection and investment castings

These services support faster iterations, minimize tooling errors, and bring your designs to life with precision and speed.

Global Procurement & Resource Sourcing

Our manufacturing relationships allow us to assist with global sourcing, vendor development, and procurement coordination. From tool steels to precision machining vendors, we help streamline your supply chain and reduce time-to-production.

Let's Build the Future of Manufacturing-Together

With over 25 years of experience in CAD, CAE, and PLM-driven engineering services, NESTech transforms design data into real-world manufacturing success. From concept to tooling to shop floor, we're your engineering partner every step of the way.
