All precision engineering processes require angle plates for keeping materials in place while they are being fabricated. For the outcome to be precise and accurate to the finest details, it is quintessential for the plates to have fine measurements and adequate durability for being able to handle the stress that is generated on the materials during the process.
Apart from tooling needs and machining processes, the precision angled plates are also useful in maintaining the accuracy of the layout in keeping with the design of the product. By keeping the materials clamped in place (often in an upright position), it becomes fairly convenient to fabricate the materials.

In accordance with various fabrication needs, angled plates are manufactured in different sizes for accommodating different sizes and shapes. The following is a discussion as well as an examination of these plates and their benefits/applications.
Defining Angle Plates:
Angle plates are devices which find their use in holding work in metalworking and fabrication wherein the plates act as fixtures for providing stability to the work material. The foremost requirement for the composite material of the plates is that it should be of very high quality so as to be able to bear the high stress and forces generated during the machining process.
The most common composite material used in the plates is spheroidal cast iron that is stabilized further to ensure that the plates do not distort or move during the process. For making the attachment of the plates to the work secure, T-Bolts / slotted holes are made on the surface. Not only does this enable getter gripping of the work, but it also keeps the plates stable on the worktable.
General Features of Precision Angle Plates:
- All standard plates comply with IS 2554 specifications.
- The surface of the plates is usually webbed with slots that have been cored on both surfaces for providing better clamping capabilities.
- The general composite material for the plates is close-grained plain cast iron wherein the composite material needs to have minimum compliance with FG 220 grade of IS: 210. This is the minimum requirement and manufacturers may also opt for composite materials that exceed the minimum compliance criteria.
