Solve Our EMI Challenge

EMI/EMC shielding + precision enclosures

One partner for EMI/EMC compliant

shielding and precision engineered enclosures.

SSD Polymers designs and manufactures conductive gaskets, shielding components and precision metal enclosures — so the groove, the gasket and the box are engineered together, by one accountable team.

Our core strength

Integrated EMI/EMC shielding and precision enclosure manufacturing.

Most programmes buy gaskets from one supplier and enclosures from another — then discover the problems at the seam. With SSD Polymers, one engineering team owns both, and you have a single point of contact from drawing to delivery.

The usual way · two suppliers

Gasket supplier

Groove tolerances and gasket compression specified separately

With SSD Polymers · one point of contact

SSD Polymers · enclosure + shielding

Your team

✓

Groove and gasket designed together, for the right compression

✓

Conductive finishes such as chromating matched to the gasket

✓

One supplier to qualify, one PO, one schedule, one accountable team

EMI/EMC shielding

Conductive elastomers, wire mesh gaskets, honeycomb vents, shielding windows, tapes, paint, putty and adhesive.

Precision metal enclosures

CNC machining and turning, laser cutting, CNC press brakes, TIG and laser welding, chromating, painting and laser marking.

What it means for you

Fewer suppliers to qualify and manage

Fewer failures at the enclosure seam

India’s first indigenous conductive gaskets.

Developed in the late 1980s, when there were no machines to buy and almost no one in India knew the product. So we designed the process, built the machines and created the test methods ourselves.

How we work

From your drawing to a qualified assembly.

A part is finished when it has been tested and documented for your platform — not when it leaves the mould. Bring us in at the design stage and the solution is usually simpler and cheaper.

Start at the design stage

01

Design together

Shielding analysis, material selection, and the enclosure groove and gasket profile designed as one interface.

Output · interface drawing and material recommendation

02

Tool & prototype

Moulds, fixtures and special-purpose machines made in our own machine shop, so iterations take days rather than vendor cycles.

Output · prototype gaskets and enclosure

03

Manufacture

Moulding, CNC machining, sheet-metal fabrication, welding and surface treatment under one roof, with the fit checked as an assembly.

Output · production parts, one schedule

04

Test & qualify

Inspection to MIL standards in-house and at NABL-accredited laboratories, with documentation and support through your qualification.

Output · test reports for your qualification file

06

Industries

Built for platforms where failure isn’t an option.

From high-altitude posts to desert ranges and the coast — each grade is specified for its own temperature range and environment.

Imported shielding was prohibitively expensive for a low-cost radar programme. SSDP invested in tooling and repeated design iterations until the indigenous solution met every requirement.

1970

A cottage industry for optical products, then rubber products for automotive and oil & gas.

Late 1980s

India’s first indigenous conductive gaskets — and the machines to make them.

Today
