Machined Components

These are made mainly for the diesel engine industry, and are made of tough alloy steels, mainly En-19, and are hardened and ground.

Our NPTF Taper Plugs are made in 25 different sizes and shapes and are made mainly from plain carbon steel. Hexagonal or square sockets are punched for tightening. Anti vibration thread sealant is applied on all such plugs. Step limit type thread ring gauges are used for maintaining thread size and consistency in order to prevent any chances of leakages from plugged joints. Our straight plugs are made with copper washer sealing grove construction, and are in metric or BSP Sizes. Form tools are used for machining of critical sealing grooves, consistency in order to prevent any chances of leakages from plugged holes.

Our product range includes around 10 various plungers used in pressure regulators for diesel engines. Typical sizes currently purchased by our customers are from 1¡¨ to 1.75¡¨ diameters (25mm to 45mm). These plungers are made from case carburising steel, which is machined on CNC machines, followed by hardening and tempering. This is followed by precision grinding to sizes and roundness parameters within 5 microns, after which the plungers are lapped to achieve surface finishes within 16 ƒÝRa in inches (0.04 ƒÝRa in mm). A strict first piece and in-process inspection system is in place to minimize defects. These plungers are then deburred in a special vibrofinishing machine to get rid of any residual micro burrs that may have remained. Each component is then inspected visually for missing operations, damages or other non-conformances. Pneumatic pressure cleaning is followed by dipping in rust preventive oil. Sampling inspection is carried out before packaging in damage proof corrugated cartons. The plungers are thus ready for dispatch.

Our part list includes 50 types of spacers, from critical spacers for rocker injector levers, to non critical mounting spacers. Most of these are machined from plain carbon steel, and sizes range from 3/4” to 2” diameter.

We manufacture tubes for hydraulic hoses and applications, which require heavier machined construction as compared to sheet metal tubes. These typically have O-ring grooved construction, and are machined using CNC Turing Centres.
