History

The Ensinger Group was founded in 1966 by Wilfried Ensinger. [2] Initially, the company focussed on the manufacturing and sale of thermoplastic engineering plastics. Closely linked with this technology, the company worked on further development of the extrusion process and application technology. A short time after relocation of the headquarters to Nufringen, Ensinger expanded its production capabilities and began machining components from semi-finished products. In 1974, the company started developing heat-insulated precision profiles for metal window systems, and by the end of 1977, the company dispatched its first volume-produced thermal insulating profiles made of glass fibre-reinforced polyamide 6.6 to manufacturers of aluminium windows. [3] [4]

In 1980 a second plant was erected in Cham/Bavaria, facilitating the mass production of insulating profiles. In 1985, Ensinger added an injection molding division. The largest subsidiary of the Ensinger Group was established in 1986 in Washington, Pennsylvania, and in the subsequent years, Ensinger expanded internationally with branches in Europe, [5] [6] North America, [7] [8] South America and Asia.

The management of the company transitioned to the second generation in 1997. Ensinger began sales in China in 2002, and established its own production facility there in 2007. [9] A third production site was opened in Germany in 2009 at Rottenburg-Ergenzingen, focussing on injection molding. [10]

On 1 February 2022, it was announced Ensinger had concluded a joint agreement to acquire INEOS Styrolution's StyLight thermoplastic composite materials business. [11]

In 2019, Ensinger divested its segment of insulating plastic spacers for insulating glass to the Fenzi Group. [12]

Business field

Ensinger's thermoplastic polymer products are utilised across a variety of industrial sectors, including mechanical engineering, automotive aviation, and medical technology. [13] [14] [15] The company's technical solutions predominantly based on thermoplastic polymers, are also prevalent in the food industry as well as in electrical and semiconductor technologies. Often, these high -performance plastics are used as substitutes for traditional materials like metals or ceramics.

To process the thermoplastic polymers, Ensinger uses a number of production methods, in particular compounding, extrusion, machining, injection moulding, casting, sintering and compression molding.

The range of polymers processed by Ensinger includes engineering plastics such as polyamide (PA), polyethylene terephthalate (PET), and polyoxymethylene (POM), as well as a category of temperature-resistance-high-performance plastics such as polyether ether ketone (PEEK), [16] polyphenylene sulfide (PPS), polysulfone (PSU), polyimide (PI), and polyimide aurum TPI. [17]

The company's organisational structure is based on a matrix system, which is segmented into different business areas reflecting its product lines including:

Compounds: During the compounding process at Ensinger, plastic raw materials are melted and extruded into thin strands with various fillers or additives, and then cut into granules. This process tailors the properties of the plastics to meet the requirements of specific applications. Ensinger has developed a range of modified plastics through this method, including products that have enhanced sliding friction values and materials engineered to possess specific electrical properties.

Semi-finished Products: Traditionally the core of Ensinger's business, semi-finished products like extruded sheets, round rods, and hollow rods are prevalent in industries such as mechanical engineering. These materials are used to manufacture small quantities of technical parts such as bearings, bushings, levers, or gears. The semi-finished products can be simply cut or subjected to more complex processes like grinding, planing, or precise machining based on specific drawings. Ensinger primarily processes construction and high-performance plastics in this segment.

Injection-molded Finished Parts: The injection molding process at Ensinger facilitates the mass production of technical parts and assemblies using high-performance plastics. Examples include thrust washers, piston rings, and ball shells for the automotive industry, along with machine elements like bearings and gears. These materials are designed to be resistant to temperature fluctuations and exposure to fuels and oils. Injection-molded parts are also utilised in medical device technology and the aerospace industry.

Polyamide Casting (Semi-finished Products): This involves pressureless mold casting to create polyamide semi-finished and finished products.

Machined Finished Parts: Ensinger also crafts finished parts from semi-finished or injection-molded components through mechanical processes such as milling and turning. This technique is often used for small production runs of technical components and prototypes, including valve pistons and transmission levers.

Industrial Profiles and Pipes: Profiles and special pipes are manufactured using controlled extrusion processes, often reinforced with materials like carbon or aramid fibers or specialised friction-reducing additives to enhance durability under mechanical, thermal, or chemical stress. Techniques like coextrusion are employed to integrate reinforcing materials or combine plastics with different properties.

Thermal Insulation Profiles: Developed for window, door, and facade construction, these profiles create a thermal break between the inner and outer metal frames, aiding in energy cost reduction. In 2013, Ensinger pioneered an insulation profile made entirely from recycled polyamide.

Other Product Lines: Ensinger's portfolio includes compression-molded polyimide materials known for their durability and strength, suitable for temperatures ranging from -270°C to 300°C, with some materials capable of withstanding up to 470°C. [18]

Furthermore, carbon fiber composites made from a PAEK-based polymer matrix (either PEEK or PEKK) embedded with carbon fibre are noted for their strength and heat resistance. These composites are primarily used in medical technology and orthopedics due to their biocompatibility and resistance to X-rays, steam, and chemicals.

Locations

The company group employs a total workforce of ca. 2,600 in 33 locations.

Production sites

The company also owns subsidiaries in Denmark, Poland, Sweden, Spain, Czech Republic, Turkey, Japan, Singapore, Vietnam, India, Taiwan and South Korea. [29]

In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst. Heat is not necessarily applied externally, and is often generated by the reaction of the resin with a curing agent. Curing results in chemical reactions that create extensive cross-linking between polymer chains to produce an infusible and insoluble polymer network.

<span class="mw-page-title-main">Injection moulding</span> Manufacturing process for producing parts by injecting molten material into a mould, or mold

Injection moulding is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals, glasses, elastomers, confections, and most commonly thermoplastic and thermosetting polymers. Material for the part is fed into a heated barrel, mixed, and injected into a mould cavity, where it cools and hardens to the configuration of the cavity. After a product is designed, usually by an industrial designer or an engineer, moulds are made by a mould-maker from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection moulding is widely used for manufacturing a variety of parts, from the smallest components to entire body panels of cars. Advances in 3D printing technology, using photopolymers that do not melt during the injection moulding of some lower-temperature thermoplastics, can be used for some simple injection moulds.

Polyimide is a polymer containing imide groups belonging to the class of high-performance plastics. With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature fuel cells, displays, and various military roles. A classic polyimide is Kapton, which is produced by condensation of pyromellitic dianhydride and 4,4'-oxydianiline.

Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product. The sheet, or "film" when referring to thinner gauges and certain material types, is heated in an oven to a high-enough temperature that permits it to be stretched into or onto a mold and cooled to a finished shape. Its simplified version is vacuum forming.

Polyamide-imides are used extensively as wire coatings in making magnet wire. They are prepared from isocyanates and TMA in N-methyl-2-pyrrolidone (NMP). A prominent distributor of polyamide-imides is Solvay Specialty Polymers, which uses the trademark Torlon.

<span class="mw-page-title-main">Microcellular plastic</span>

Microcellular plastics, otherwise known as microcellular foam, is a form of manufactured plastic fabricated to contain billions of tiny bubbles less than 50 microns wide. It is formed by dissolving gas under high pressure into various polymers, relying on the phenomenon of thermodynamic instability to cause the uniform arrangement of the gas bubbles, otherwise known as nucleation. Its main purpose was to reduce material usage while maintaining valuable mechanical properties. the density of the finished product is determined by the gas used. Depending on the gas, the foam's density can be between 5% and 99% of the pre-processed plastic. Design parameters, focused on the foam's final form and the molding process afterward, include the type of die or mold to be used, as well as the dimensions of the bubbles, or cells, that classify the material as a foam. Since the cells' size is close to the wavelength of light, to the casual observer the foam retains the appearance of a solid, light-colored plastic.

<span class="mw-page-title-main">Polyphthalamide</span>

Polyphthalamide is a subset of thermoplastic synthetic resins in the polyamide (nylon) family defined as when 55% or more moles of the carboxylic acid portion of the repeating unit in the polymer chain is composed of a combination of terephthalic (TPA) and isophthalic (IPA) acids. The substitution of aliphatic diacids by aromatic diacids in the polymer backbone increases the melting point, glass transition temperature, chemical resistance and stiffness.

<span class="mw-page-title-main">Metal injection molding</span> Metalworking process in which finely-powdered metal is mixed with binder material

Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a "feedstock" that is then shaped and solidified using injection molding. Metal injection molding combines the most useful characteristics of powder metallurgy and plastic injection molding to facilitate the production of small, complex-shaped metal components with outstanding mechanical properties. The molding process allows high volume, complex parts to be shaped in a single step. After molding, the part undergoes conditioning operations to remove the binder (debinding) and densify the powders. Finished products are small components used in many industries and applications.

Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers (TPR), are a class of copolymers or a physical mix of polymers that consist of materials with both thermoplastic and elastomeric properties.

<span class="mw-page-title-main">Plastic extrusion</span> Melted plastic manufacturing process

Plastics extrusion is a high-volume manufacturing process in which raw plastic is melted and formed into a continuous profile. Extrusion produces items such as pipe/tubing, weatherstripping, fencing, deck railings, window frames, plastic films and sheeting, thermoplastic coatings, and wire insulation.

Fusible core injection molding, also known as lost core injection molding, is a specialized plastic injection molding process used to mold internal cavities or undercuts that are not possible to mold with demoldable cores. Strictly speaking the term "fusible core injection molding" refers to the use of a fusible alloy as the core material; when the core material is made from a soluble plastic the process is known as soluble core injection molding. This process is often used for automotive parts, such as intake manifolds and brake housings, however it is also used for aerospace parts, plumbing parts, bicycle wheels, and footwear.

Nylon 66 is a type of polyamide or nylon. It, and nylon 6, are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name. Aside from its superior physical characteristics, nylon 66 is attractive because its precursors are inexpensive.

<span class="mw-page-title-main">Filler (materials)</span> Particles added to improve its properties

Filler materials are particles added to resin or binders that can improve specific properties, make the product cheaper, or a mixture of both. The two largest segments for filler material use is elastomers and plastics. Worldwide, more than 53 million tons of fillers are used every year in application areas such as paper, plastics, rubber, paints, coatings, adhesives, and sealants. As such, fillers, produced by more than 700 companies, rank among the world's major raw materials and are contained in a variety of goods for daily consumer needs. The top filler materials used are ground calcium carbonate (GCC), precipitated calcium carbonate (PCC), kaolin, talc, and carbon black. Filler materials can affect the tensile strength, toughness, heat resistance, color, clarity, etc. A good example of this is the addition of talc to polypropylene. Most of the filler materials used in plastics are mineral or glass based filler materials. Particulates and fibers are the main subgroups of filler materials. Particulates are small particles of filler that are mixed in the matrix where size and aspect ratio are important. Fibers are small circular strands that can be very long and have very high aspect ratios.

Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.

A thermoset polymer matrix is a synthetic polymer reinforcement where polymers act as binder or matrix to secure in place incorporated particulates, fibres or other reinforcements. They were first developed for structural applications, such as glass-reinforced plastic radar domes on aircraft and graphite-epoxy payload bay doors on the Space Shuttle.
