Plastic injection molding

Injection molded parts made from high-performance plastics. Whether you need precise functional parts for medical technology, resilient components for aviation or complex geometries for mechanical engineering, we develop and manufacture custom injection molded parts from high-performance plastics that work where other materials reach their limits. 

As an internationally positioned family-owned custom injection molding manufacturer with over 50 years of experience, we accompany your product idea from the initial sketch to series production – in close co-operation, with a wealth of engineering expertise and a clear goal: the optimal solution for your application. 

We supply renowned OEMs with OEM injection molding solutions in a wide range of industries worldwide – including medical, aviation, industrial and automotive engineering – and have established industry-proven, standardized processes that ensure quality, traceability and efficiency along the entire value chain. 

With our injection molding factories in the USA, Germany, China and Brazil, we stand for quality, customer proximity and reliable series production worldwide – no matter where your project starts. 

What sets us apart: 

• Precision injection molding in series production: Fully automated manufacturing with state-of-the-art machinery
• Engineering expertise: In-house development, simulation and toolmaking
• Material diversity: Access to over 100 modified thermoplastics – including compounds developed in-house for thermoplastic injection molding and thermoplastic molding 
• Certified quality: ISO 13485, IATF 16949, ISO 9001 
• Global presence: Production capacities in Europe, North and South America, and Asia 
• Sustainable thinking: Recyclates, bioplastics, and a commitment to the circular economy 
• The reliability of a family-owned company: Long-term, partnership-based, responsible

Not every application can be solved with classic injection molding. That is why Ensinger also offers a range of specialized manufacturing processes that enable us to produce complex, multifunctional or high-precision plastic components economically – even in series production. 

Ensinger is your global technology partner for precise plastic injection molding parts with tight tolerances and complex geometries. As a specialist in precision plastic injection molding, we combine high-performance plastics with in-depth process knowledge and qualified engineering support – from the initial CAD model to certified series production. 
Thanks to our process-reliable manufacturing, even very tight tolerances and specifications can be reliably met (dimensional tolerances < 0.02 mm). 

Choosing the right plastic is crucial for the function, service life and manufacturability of a component. Ensinger processes a wide range of thermoplastic materials – from engineering plastics to high-performance polymers – precisely tailored to the requirements of your industry. 
Thanks to our connection to Ensinger compounding, we also offer you the option of processing customer-specific modified materials – for maximum functionality and cost-effective series production. Among others, we use: 

A successful plastic component starts with the right process. 
At Ensinger, we support your development every step of the way – with technical advice, in-depth material knowledge and modern project management. Our offering goes far beyond mere manufacturing: we deliver solutions – comprehensive, structured and transparent. 

Ensinger sets the highest standards for quality, safety and traceability throughout the entire life cycle of an injection molded part. The quality management system (QMS) is established worldwide at all locations (Germany, USA, Brazil, China) and certified according to ISO 9001:2015. Ensinger also complies with industry-specific standards such as ISO 13485 (medical technology), IATF 16949 (automotive), AS9100D (aerospace) and other specific standards. 
In practice, Ensinger relies on automated in-line testing processes and a comprehensively equipped measuring laboratory with, among other things, tactile 3D measuring machines, contour measurement, roughness analysis and special tests. 
Quality begins with design. FEM analyses, filling and process simulations as well as FMEA are used as early as the development phase to identify and avoid risks at an early stage. The entire product development process complies with standards such as APQP and PPAP. 

Are you looking for a development partner who is on the same wavelength as you – globally accessible and with a family-oriented mindset?
