Drilled & Milled plates

Drilled & milled plates are perforated by machining with multi-spindle heads or special multi-tool milling heads. This process enables perforations to be achieved, which are substantially smaller in size than the thickness of plate, enabling high open area screens with small hole section. Thus, making them suitable as filter screens or separating screens for special machines and presses as used in the food, paper & pulp, milling and sludge treatment industries.

Perforation by machining enables a variety of hole sections to be achieved covering – conical, stepped, cylindrical, with perforations at 60, 45 degrees or straight.

As with perforated plates, screens for flour Milling, food processing, paper & pulp screens can be offered in several materials and finishes.

Drilled perforated filter plates hole sizes are available from 0.8mm to 10mm.

Perforated plates parts, baskets, hammer mill screens, cylinders and trays

An extremely diverse range of punched plate, drilled plate and milled perforations, plus a variety of wire meshes, provides a basis for fabricating baskets, cylinders and screens to suit individual designs.


Perforated baskets and cylinders

An extremely diverse range of punched plates, drilled plate and milled perforations, plus a variety of wire meshes provides a basis for fabricating baskets, cylinders and general screens to suit individual designs.

These can be supplied with flanges end on end, stiffening rings and diverter plates with final machining to suit process requirements, as specified in pulp and paper screens for filtration and separation and many screens for the food and chemical processes.

Screen baskets and screen cylinders can also be fabricated from a combination of wire mesh, perforated sheets or wedge wire in a variety of materials for applications covering de-watering and effluent.

Hammer mill screens

From a wide range of perforated plates, we are able to produce screens or sieves for many types of hammer mill.

Perforated trays

Chemical and petrochemical industry requirements for distillation trays can be produced to suit specific process parameters. These can be met where special perforated configurations are called for, which often dictate the need for individual tailormade dies.

Fortunately, Costacurta has gained considerable experience in the production of small hole perforations and has the ability to perforate materials where the punched hole diameter is required to be smaller than the plate thickness. Trays can be supplied in one piece or multiple section.
