PMMI (Polymethacrylmethylimide) is a thermoplastic polymer. As it is an amorphous polymer, it features high transparency. The case study describes how thermal analysis methods can be employed to discover everything about the material.
Bringing cost, material, production process and quality successfully together is one of the key objectives in the injection molding industry. If the production process is not correct or if the material does not adhere to the specified requirements, low quality and thus scrap production is the consequence. Ideally, all of these four factors should be able to be managed in order to avoid scrap production. Thermal analysis methods offer valued approaches.
Knowledge of the thermal properties of the material is crucial for producing thermoplastic parts. However, materials are not always delivered with sufficient information on all properties. Thermal analysis instruments are suitable to find the most important parameters by yourself. But the instrument is only the first step. The software is equally important. Here are two examples how Proteus® can help achieve faster results.
Thermoplastic parts can fail. This is no secret. However, when it has happened it is crucial to find out the reason for the failure of a part. Here is a short list of thermal analysis techniques and which questions they can answer in your failure analysis.
Additive Manufacturing (AM) has been around for several years. The main application for a long time was prototyping in the early stages of product development. Recently, new technologies like Digital Light Synthesis (DLS) are shaking up the AM sector. Using DLS and a two-stage dual-curing process, 3D printing is now being considered for mass production of parts since it has become considerably faster and the final product shows improved mechanical characteristics.
Failure of injection-molded thermoplastic parts appear in a wide range of forms. Often, the selected material or the production process of parts and components are the cause of the problem. Whenever faulty parts leave the machine, it is important to find the underlying cause of the failure. We selected two common failures of thermoplastics and show how thermal analysis can help determine the cause of failure.
Industrial 3D printing processes create functional, end-use parts with mechanically isotropic properties and smooth surface finishes. Read how Prof. Dr. Tim Osswald, Alec Redmann and the team at the University of Wisconsin-Madison worked together with the California-based company Carbon Inc. optimized the thermal curing cycle of EPX 82 resin used in the their Digital Light SynthesisTM (DLSTM) process.
Four technology-driven trends disrupt the automotive industry and transform mobility as we know it today. Our future cars will be autonomous, electric, shared and connected. Polymer parts and components will not become redundant. They will rather be used for different applications. Learn which material properties are crucial in tomorrow’s cars.
Every delivery of thermoplastic material includes a certificate. The European Norm EN 10204 specifies different types of control documents. However, the data contained in the free-of-charge documents are often not sufficient enough. Obtaining specific material data of a delivered batch is tied to additional cost. Read how to become the owner of your material data.
Corex Plastics (Australia) Pty Ltd is a leading manufacturer of twin wall profile Fluteboard® and Corflute® sheet and solid sheet extrusions. The company’s closed loop philosophy forms an integral part of its business, but also posed some challenges for the company. With the recycling business growing, there was an enhanced need for adequately sorting feed streams and controlling quality of recycled resins. Thermal analysis instrumentation from NETZSCH is the solution to their problems.
