Research and Development

INDURE’s R&D is a strong technological backbone of the company. It is a unique one-stop solution provider for complete product development.

INDURE offers specialised engineering services to customers in developing complex mechanical designs and products, enabling them to reduce development time & cost significantly.

A proven track record of providing complete mechanical engineering solutions for customers in various sectors viz. thermal power, hydro power, solar power, cement, steel and mining etc.

Innovative conceptual design is the core of any successful product. R&D quickly captures, develops, and communicates design ideas directly into the digital model with Solid Works to accelerate development, decide the product’s mechanical architecture, simultaneously select the material and processes giving a real look and feel of the product.

3D solid model is created which is a critical aspect for modern product development and provides the basis for design, simulation, and manufacturing of any part and assembly across a broad range of applications and products. It eliminates design interference isuses, checks design functionality and performance (without the need for physical prototypes), automatically provides manufacturing with 3D solid models that are required when programming CNC machine tools and rapid prototyping equipment.

Structural analysis for assemblies with SolidWorks simulation enables us to efficiently analyze product behaviour under mechanical conditions taking into account the physical relationship between the parts of the equipment to ensure high quality, performance and safety. Every product is made of several components or bodies. Defining how these parts connect to each other is crucial for an accurate structural simulation during the product development process. Analysis of assemblies is a regular part of our design process, reducing the need for costly prototypes, eliminating rework, delays subsequently saving time and developments costs.

Preparation of production-ready 2D drawings that are always current and clearly communicate how the product design should be manufactured and assembled. Preparation of bill of materials, CNC Data, Maintenance Instruction Manuals, Color schemes, High quality life-like images and animations are also taken care of.

Quality Assurance

Quality Assurance and Inspection

The Quality Assurance programme encompasses the complete cycle from design to detail engineering, manufacturing installation and commissioning. A systemised procedure of “Quality Control” from raw material to finished product is rigorously maintained as per written procedure of Quality Assurance Plan.

INDURE fully recognises the need for an emphasis on quality and all its members strive achieve excellence in their designated work which has enabled it to gain recognition, reputation and regular clientele for its products.
