Plastic Precision Injection Molding
Marlee – Texen support you determining the best tool concept and resin selection.
Plastic Precision Injection molding is often used in creating precise surgical equipment that has a low shrinkage tolerance.
High plastic precision injection molding is often used to create smartphone parts. They are small-scale and require high precision.
Certain Automotive parts have very low shrinkage tolerance and therefore use high plastic precision injection molding to create them.
Polycarbonate (PC) is quite an efficient material that is amorphous and transparent in nature. It is a type of thermoplastic used in manufacturing a wide variety of shapes and sizes of plastic. PC injection molding is one of the best choices for manufacturing custom-tailored plastic because of its highly flexible and impact-resistant qualities.
Polypropylene(PP) is a thermoplastic resin used for its flexibility and strength. It has a very low density and is suitable for scientific molding. Its flexibility and resistance find much application in packaging sensitive material. PP is an “addition” polymer, made from the linking of many polypropylene monomers.
Polyethylene or polythene is the resin made from the polymerization of ethene. PE is the most versatile synthetic resin. It has a crystalline structure and can be high density (HDPE) or low density (LDPE). It is used by the packaging and plastic manufacturing industries.
Nylon resins are durable and have excellent strength. The polyamide structure also gives it high-temperature tolerance and density. Nylon also has wide-ranging uses due to its many useful properties. It is elastic, has high tensile strength and oil resistance as well. Therefore, it is commonly used in the automobile industry, packaging, construction material and electronic components.
PC/ABS combines the strength of PC and the flexibility of ABS, making it ideal for use by a custom plastic molding company. TPE and TPU are thermoplastic elastomers. They are used for making lids, sports goods, power tools, medical device parts, etc. They are used in these industries for their abrasion resistance and elasticity.

Precision injection molding is a highly technical process that requires the use of precision molds for the production of complex plastic components. This process is characterized by its ability to produce parts with tight tolerances, high surface quality, and intricate geometries, making it ideal for applications where accuracy and detail are critical. The process involves heating plastic pellets until they become molten, then injecting them into a precision mold under high pressure, resulting in highly detailed and consistent parts.
Compared with standard injection molding, precision injection molding requires higher precision and superior surface quality for the molded parts. This process imposes special requirements on the injection molding machine, mold, molding process, and materials used. The machinery and processes must maintain strict control over variables such as temperature, pressure, and cooling rates to achieve the desired precision.

Key benefits of precision injection molding include the ability to produce detailed and complex geometries, high efficiency and fast production cycles, strength and versatility of materials, capability to use multiple types of plastic simultaneously, cost savings through reduced waste and optimized processes, high precision and tight tolerances, shortened product development time, and multiple finishes and surface textures.
Marlee – Texen ensures consistency and quality through meticulous machine calibration and process control. This includes maintaining precise control over injection pressure, melt temperature, cooling rates, and part ejection. Regular maintenance and calibration of machinery, combined with rigorous monitoring of process parameters, ensure reproducible results and high-quality parts.
The tolerances achievable with precision injection molding range from +/-0.1mm for common parts to +/-0.025mm for parts requiring high precision. These tight tolerances ensure that the parts meet stringent specifications and performance standards.
Precision injection molding supports tight tolerances and intricate details through the accuracy and repeatability of the molding machines. High-pressure injection machines ensure better material flow and fill intricate mold features more effectively, resulting in precise and detailed parts. Tight process control and advanced mold design also contribute to achieving the desired specifications.
Marlee – Texen’s precision injection molding process reduces waste and improves sustainability through energy-efficient operations and precise material use. The process minimizes excess material by accurately controlling the injection and mold filling. Additionally, modern precision molding machines often use less energy, further reducing the environmental impact. Recycling scrap material and using sustainable materials also contribute to a greener manufacturing process.
Marlee – Texen’s precision injection molding facilitates prototyping and product development by allowing rapid production of high-quality prototypes. These prototypes can be used for functional testing, design validation, and market evaluation. The ability to quickly produce accurate models accelerates the development process and helps identify and resolve design issues early.
