Shearing and slitting are manufacturing processes in which metal sheets are cut in straight lines. Shearing takes place at the ends of the sheets, while slitting is used to cut wide metal rolls into narrower sheets.

During the SLS process (selective laser sintering) a carbon dioxide laser is drawn into a bed of thermoplastic powder, fusing (sintering) the powder into a solid. It is exceptionally accurate, can be used with a range of materials, and has a number of finishing options.

06/03/2021

The speed, pressure, and size of a water jet are so great that they are often referred to as water lasers, and they work in the same fashion. They can cut completely through materials, or can be used like a router to create delicate inlays and patterns during manufacture.

06/01/2021

Each facet of the manufacturing industry has different needs, and one-size-fits-all equipment is a bad investment. When we develop machines and equipment designed for your specific needs, you are assured of products that are highly efficient and tailored to the demands of your environment.

05/27/2021

Injection molding can be used to manufacture materials for a range of industries. Plumbing parts, optical lenses, aerospace components, as well as parts for specialized industries and applications can all be made using this process.

05/25/2021

High-speed manufacturing of heat-resistant super alloys and other hard metals can be best accomplished using whisker reinforced ceramic inserts. They create a sharper insert edge which produces better surfaces finishes because of reduced tool pressure.

05/20/2021

If tooling is what you need, CNC grinding is accomplished through a seven-axis machine to create taps, drills, reamers, and other items out of any material. It dominates in the machining of medical tools and the manufacturing of tools to make custom parts.

05/18/2021

If you need a new or replacement SMC slitter for your manufacturing operations, our engineers will work with your design specs, to produce a machine that meets your needs. We can deliver both dual-cycle or single-cycle set-ups.

05/13/2021

For producing longer cuts and manufacturing heavier parts, Swiss machining is a more effective process than what can be produced with a standard CNC turning lathe. Its multi-axial configuration also reduces secondary processes.

05/11/2021

In hydraulic manufacturing equipment, the fluid, when under pressure, is stored in an accumulator. The liquid in this container is used to absorb shock, to provide energy, or to increase or decrease pressure. Accumulator designs include bladder, piston, and diaphragm.

05/06/2021

How many items can you cut from a piece of stock? Obviously, that depends on the size of the piece. However, nesting software allows for planning out the process so that the maximum number possible is cut from each piece of stock.

05/04/2021

Because our special and custom designed manufacturing equipment must be durable and stand up to heavy, often around-the-clock use, we use only the highest quality name-brand components when creating equipment for our customers.

04/29/2021

Because it is an additive manufacturing process, selective laser sintering (SLS) utilizes layering as a roller places a new fresh powder on top of the bed and the laser steps are repeated as needed during the manufacturing process.

04/27/2021

For medium to heavy stainless, steel alloys, and aluminum and aluminum alloys up to an inch in thickness, high definition plasma cutting is a sound economical choice for manufacturing runs that allow for rougher edges and less precise tolerances.

04/22/2021

Intersecting shafts are connected using bevel gears and they can be set at, below, or above ninety degrees. In addition, there are multiple tooth designs employed, depending on the manufacturing process.

04/20/2021

If the parts being manufactured will eventually be welded, water jet cutting is the superior method. The process creates a sandblasted surface so that prep time is reduced and a finer, stronger weld can be created.

04/15/2021

For joining delicate or fragile materials during manufacture, boring a countersink prior to fastening cuts down on breakage. If you already have them, step drills perform this function quite well, and will save the cost of purchasing more inventory.

04/13/2021

Oxidization of part edges during the manufacturing process can cause problems from fit to paint adherence. Laser cutting equipment removes oxidization and puts a slight chamfer on the edge allowing for proper powder coasting or paint adherence.

04/08/2021

CNC machining has some significant advantages. It can be programmed to handle high-production cycles while delivering uniform results with minimal labor requirements making it exceptionally cost-effective.

04/06/2021

While CNC machining is superior for production runs up to 1,000, multiple spindle automatic machines are preferred for runs over this number, especially for those parts with features that are attached perpendicular to the exterior plane.

04/01/2021

Water jet cutting is a safe alternative to traditional methods of parts manufacture. It is especially good for precision cutting of materials easily damaged by other methods.

03/30/2021

In addition to their dependability, strength, and durability, our efficient and reliable SMC slitters can be adapted to fit any work environment in order to meet even the most demanding production conditions.

03/25/2021

Because of the fine stream of water used in water jet cutting equipment, more precise cuts can be made, and there is less waste. This means you can get more product from any given sheet of material.

03/23/2021

Milling machines are used for cutting or shaping wood, metals of all kinds, and plastics, and they are labeled according to their degree of motion and work piece orientation. The mills themselves are outfitted with tool heads, which are determined by the material being milled.

03/18/2021

Laser technology delivers precise work on materials that require extremely precise cutting. It is a sound alternative to traditional stamping and manufacturing processes, and is recommended for metals requiring cut consistencies between 0.002” and 0.003”.

03/16/2021

There are many methods of rolling metal – flat, foil, profile, ring, and more. Hot rolling produces the most tonnage of all the manufacturing processes; cold rolling delivers the most tonnage of the cold working methods.

03/11/2021

Egyptians are generally believed to have created some of the first rudimentary welding techniques. During the Bronze Age, they started melting iron and by around 1,000 BC they had perfected a technique to make solder.

03/09/2021

Woodworking lathes can perform up to 1,400 revolutions per minutes. To put that into perspective, most woodworking applications only require 1,000 revolutions per minute.

03/04/2021

How much power does a laser cutter require? Well, a laser cutter needs around 6000 watts of power to operate, which is good enough to cut any material.

03/02/2021

The preventive maintenance of manufacturing equipment involves regularly servicing the equipment to reduce the possibility of an unexpected breakdown. It avoids the consequences of failure, such as increased costs and loss of revenue.
