For instance, it improves production speed by helping to release the part from the mold faster. The image shows the result of a fill analysis that predicts the polymer flow in the mold. This is one of the common analyses used to verify the quality of the mold design and process.

Injection Molding of Plaques A Milacron injection molding machine was used to prepare plaques for the measurements of physical properties and adhesion. They have good flow characteristics suitable for injection molding applications. These TPEs also possess good flow properties suitable for injection molding applications.

Recently Launched Colorant Chromatics™ Evoluscend™ Non-PFAS High-Temperature Mold Release Additive: a high-temperature polymer mold release additive made without intentionally added PFAS and developed to boost production efficiency and product quality for manufacturers. Mevopur™ Healthcare Colorants and Functional Additives: formulations pre-tested to support compliance with regulatory requirements, such as USP Class VI, ISO 10993, EP3.1, USP661.1, and ICH Q3D and manufactured across a global network of ISO 13485-certified facilities or under GMP certifications.

However, the molded thermoset composites traditionally used in binding applications are often brittle and lack the processing versatility to allow for significant customization. Injection overmolding with thermoplastic composite laminates combines the advantages of injection molding—the ability to create complex shapes and fast cycle times—with the lightweight strength and durability of continuous fiber reinforcement. And, unlike thermosets, thermoplastic materials are able to be easily thermoformed to the exact shape required before inserting into the injection mold.

Design freedom = unique product offering: The ability to injection mold Gravi-Tech materials instead of machining brass enabled API to design a cost-effective, full-opening flapper valve that is 100% pigable Use of existing tooling = lower capital costs: API was able to use the same mold originally designed for nylon to run the Gravi-Tech materials, saving the substantial costs of retooling. Thanks to the customized Gravi-Tech material, API was able to successfully design and mold a flapper valve that is the only one of its kind on the market—and offers a less expensive solution than traditional brass valves.

In order to deliver the best blow molding performance, it is customary within the conversion industry to establish ‘recipe’ guidelines per resin/per supplier as different PET resin production technologies and different specific resin formulations can significantly influence the blow molding performance. Such advice, for example how to set up blow molding machines, is not equipment specific and therefore ColorMatrix would always recommend using local or expert technicians in addition to following best practice points listed below; • Preforms should be conditioned for minimum 24 hours prior to blowing • Preforms should always be used in a FIFO manner (First In, First Out) • Octabins of preforms should be segregated and blown per resin type, i.e. not mixed with other resins • A preform traceability system should be in place such that any process upsets can be quickly followed up and corrected • Enhanced QC preform checking resources for bottle distribution, aesthetics and integrity should be on-hand during the performance optimization trials • Prior to any process optimization, the blowing machine performance should be verified as being within normal i.e. accepted standard ranges and all important components and control features are working satisfactorily. Maximum speed output should be attainable prior to any ‘recipe’ setting trials TECHNICAL BULLETIN The diagram below shows many of the variables that are typically present during stretch blow molding and this illustrates the complexity of the whole process.

Injection molding the closure from this material, called Gravi-Tech™, would provide the look, feel and sound of metal and maintain a premium perception. Switching from metal forming to injection molding would also enable processing cost savings and expanded design freedom.
