Parts

This area of the Techpilot Lexicon focuses on technical parts—from standardized components to custom-made solutions. Learn where specific parts are used and how to evaluate them properly. A practical guide for making strategic purchasing decisions.

• Circular honing

  A hydraulic cylinder is a working cylinder which converts the force of a hydraulic energy source into a linear movement. Hydraulic cylinders play an important role in power transmission, especially in vehicles and machines. Hydraulic cylinders convert hydraulic into mechanical energy and are capable of transmitting very high forces. A further advantage of hydraulic drive technology is the possibility of imaging particularly uniform and exact driving movements. The hydraulic cylinder makes use of the low compression of hydraulic fluids.

• Gravity casting moulds

  A mold is a metallic mold used for the production of precise workpieces with good surface quality. Moulds often consist of cast iron or copper plates and are widely used in metalworking industry. The mold is the technical basis of the mold casting process and has proved successful in the production of large forging blanks, slabs for sheet metal products, billets for wire, rod and profile products and other components. In the mold casting process, the metallic melt is poured into the mold via the above-lying injection and cures there. Depending on the casting process, a mold can be used up to 100,000 times, resulting in a high cost.

• Make or buy

  The term Make-or-Buy refers in the economy to the entrepreneurial decision between own production (Make) or the foreign cover (Buy). The make-or-buy decision is particularly important in industrial manufacturing processes. In principle, the question “Make or Buy?” is relevant for all activities of the company value chain. From a company-strategic perspective, the question is closely linked to the extent of the vertical integration of the company. From an operational point of view, I usually consider the outsourcing of production steps to be an economic consideration.

• Mechanical engineering contract manufacturing

  Machinery engineering is one of the classic engineering sciences and covers the fields of development, construction and production of machinery and equipment. Mechanical engineering is based on scientific and engineering principles such as mathematics, mechanics, thermodynamics and material science. Mechanical engineering wage production is in many contemporary everyday objects: from the sewing machine to the coffee machine to the aircraft. Mechanical engineering wage production is more relevant than ever: vehicles must become more energy-saving, production paths more efficient and the use of materials and resources more economical and environmentally friendly.

• Con rod

  A connecting rod is also referred to as a connecting rod or push rod and connects the crankshaft to the piston in a crank drive. The connecting rod converts the linear movement of the piston into a linear oscillating axial movement and thereby allows the force transmission in the vehicle train. As a rule, connecting rods are made from C70 steel or from microalloy steels. In addition, compensation steels or titanium are also used in the sports motor sector. Connecting rods in large series are frequently forged, sintered or cast, whereas in productions with small numbers a cutting production of metal pieces is preferably used.

• Injection molding tool

  The injection molding tool is a continuous mold used to produce components with an injection molding machine. The injection molding tool usually consists of metal and has a cavity which determines the shape and surface structure of the produced part. During injection molding, the injection molding tool is filled with plasticized plastic under pressure. Subsequently, the material cools down in the injection molding tool and thereby hardens. After the tool has been opened, the molded part can be removed. Injection molding tools are used to produce various components with weights of a few tenths of grams up to 150 kg. The process enables economical and efficient series production and therefore enjoys great popularity in the plastics processing industry.

• Steel profiles

  Steel profiles are steel components which have the same cross-section over their entire length. Steel profiles are usually produced by rolling, drawing or pressing and are used as construction steel or for the production of rails, ladders or struts. When using steel profiles, it is crucial to tune the decisive material or component parameters to the application. It should be ensured that the static moment, the moment of resistance and the moment of inertia of the surface correspond to the load requirements of the respective application.

• Custom made part

  As a part of the drawing, the metal and plastic processing industry describes a custom production. Drawing parts are produced individually for a customer, using a variety of over milling to punching and pressing. In industry, drawing parts are particularly relevant for special applications. If the customer cannot rely on a standardized standard application for his application, he applies to a contractor that can supply the desired component as a part of the drawing. In addition to a drawing, a CAD file or a pattern can also serve as the basis for production.
