We Know a Whole Lot About Holes
Hendrick Manufacturing Perforated Metal Processes
Perforation makes products work better and it enhances their aesthetic qualities. We can produce unlimited patterns from standard to intricate configurations in a variety of shapes. We also offer in-house cleaning, degreasing, deburring and polishing services. Our goal is provide you with the highest-quality product that meets your exacting specifications.
Our Perforating Capabilities
- Round, square, slotted, ellipse, hexagon and a variety of decorative patterns
- Perforation sizes from 0.020" up to 6" in diameter
- Punch, laser and plasma capabilities
- Wide range of popular materials in stock; we perforate steel, copper, plastic and stainless steel
Our Process Capabilities
Hendrick adapts the perforating process to meet the project’s exact requirements for hole placement, materials and shape of the part. Plus, we can create perforated patterns with the customer’s desired blank areas, margins, hole spacing and more — all to very tight tolerances.
Perforated metal is manufactured from sheets or coils using electronically controlled presses. Every press, each with its own working width, accurately punches hole patterns. There are different machine operations used to perforate materials, and each one has its manufacturing advantages. Hendrick offers the following options at our Pennsylvania and Illinois manufacturing facilities.
All-Across, Full-Width Perforating
This is our core capability. All-across presses are designed to quickly and correctly produce the greatest number of holes per hit — up to 1,600 per stroke, which makes this the fastest, most efficient and most economical perforating method.
The all-across, full-width perforating process is typically used for larger runs. Our high-speed perforating presses are capable of punching material up to 60" wide in thicknesses ranging from 0.002" to 0.25". Punch hole size dimensions are from 0.027" to 2.0" in diameter. All-across punches punch up to 600 strokes and 300,000 holes per minute.
Using various tools, we punch perforated metal made from steel, stainless steel, aluminum, brass, copper, titanium, and can even do plastics and other materials to produce practically any hole pattern and blank areas where desired. Plus, CNC punching can provide value-added operations simultaneously, such as cutouts, mounting holes and notches.
This cost-effective, accurate and repeatable method is suitable for punching sheet metal in prototype, low-volume or production runs. Our 20- to 55-ton presses produce components in various widths and materials, and our high-precision equipment can meet your tight tolerances.
Laser or Plasma Cutting
Regardless of the material type or thickness, we have the versatility to produce parts with very intricate geometries and precise dimensions using our laser or plasma cutting equipment. Plus, our punch/plasma combination machine performs multiple operations that can reduce production costs.
There are many industries and applications that use perforated metal. Among them are: acoustical cabinets, appliances, architecture, electronic enclosures, farm equipment and vehicles, filtration, food and beverage processing, grain dryers, guards, HVAC, lighting fixtures, panels, partitions, pharmaceutical, retail displays/fixtures, screens and transportation.
A wide choice of perforated patterns is available. We offer a variety of shapes, sizes and materials, including, but not limited to:
- Round holes, staggered or straight patterns
- Slotted holes, staggered or straight patterns
- Square and rectangular holes, staggered or straight patterns
- Diamond, elliptical and hexagonal holes, staggered or straight patterns
- Decorative patterns such as cloverleaf, in staggered or straight patterns
