ENGINEERING

Engineering being our core, any project undertaken, may it be a simple component or a complex assembly, flows through our following engineering proficiencies to achieve techno-commercial finesse in the array of manufacturing of Springs & Wire Forms.
ENGINEERING EXPERTISE FOR COST EFFECTIVE PRODUCTS

Our comprehensive and practical knowledge of various International Spring Standards such as EN,DIN, JIS, ASTM, mater...ials and manufacturing processes such as Hot Coiling, Cold Coiling,Wire Forming etc. enables us to select the most suitable combination of processes and machines that in turn achieves the most desirable Cost / Precision / Volume / Time efficiency matrix.

IN-DEPTH UNDERSTANDINGS OF CLIENTS' REQUIREMENTS

Having penetrative abilities to understand clients' product key attributes, its functional requirements & desi...red specifications, we contemplate on vital process parameters such as Load Deflection characteristics, Torque Analysis, Spring Rate, Fatigue Life Prediction, Modulus of Torsion and Elasticity etc. and appropriately design customized development and manufacturing plans to achieve an optimized techno-commercial product.

HANDLING INTRICATE AND ADVANCED JOBS

Our core competencies are in handling & manufacturing of intricate Types, Shapes and Sizes of Compression, Exten...sion, Torsion and Heavy Duty Coil Springs made of Wires, Flats & Tapered Wire Forms.

PREDEFINED REMEDIES TO AVOID PROCESS DEFECTS

We are apt to envisage & encounter process defects and limitations such as Non uniform Spring Rate, Loss of Tens...ion/Compression/Torque during working life, Variations in Coiling Tolerances, Failure in Fatigue Life etc. and incorporate predefined remedies while designing the manufacturing plans.

VALUE ENGG, REVERSE INTEGRATION & DESIGN UPGRADE

We stand ready with our backward integration expertise and value engineering initiatives to revisit design param...eters and render optimum manufacturability solutions such as suggesting alternate alloys to improve coiling rate, optimizing spring design to improve strength and life for e.g. Modifying design for height Extensions in rough road conditions to maximize ground clearance with heavy duty performance.

ENGINEERING SOFTWARE APPLICATION & INFO TECH

We provide comprehensive support in product design & development using advanced tools such as 3D Software, Fini...te Element Analysis (FEA) etc. for in-depth understanding of clients specifications & by precisely recommending design alternatives, Interfacing in further assembling and subsequently assisting our tool makers & machine programmers / operators to profoundly comprehend the spring characteristics leading to an optimized production process thus adding value to clients' end product quality.

MANUFACTURING ENGINEERING & TOOLING SOLUTIONS

Our engineers have meticulous knowledge of manufacturing engineering, Tool design-development and prevent...ive maintenance systems supported by tool room for Mandrels, Forming Fixtures, Gauges and Special Inspection Devices to achieve mass production with consistent quality at minimal inspection.

ALLIANCE WITH TECHNICAL INSTITUTES & EXPERTS

Our strategic tie-ups with strong networks of consulting Technical Experts, R&D Institutes and laborator...ies dedicated to springs & its manufacturing processes assist us in enhancing our competencies.

ALLIED PROCESSES , ASSEMBLY ENGG. & TOTAL SOLUTIONS
