Injection Molded Delrin Enclosure for Blasting
A major manufacturer of electronic housings for the blasting industry partnered with Jaco Products to solve a complex manufacturing challenge that demanded high-precision injection molding of Delrin plastic to satisfy rigorous operational standards.
Injection molded Delrin product specifications overview:
The project required a two-part injection molded Delrin enclosure paired with a custom die-cut gasket. Key specifications demanded high flexural strength, electrical isolation, and reliable waterproofing at depths exceeding ten feet. During prototyping, the client requested a design update: the housing needed to be easily field-serviceable without specialized tooling.
Jaco met this requirement by integrating external reinforcement ribs into the design to maintain structural integrity and secure a castle nut. This modification enabled technicians to easily perform maintenance in the field using standard tools.
Through prototyping and field-testing, we were able to supply an enclosure that met the customer’s specifications. As a result, the enclosure is currently being injection molded in a two-part family mold using DuPont’s Delrin 100. Furthermore, this component is molded under strict guidelines to ensure part integrity and a waterproof enclosure. To aid in waterproofing, Jaco provides a die-cut gasket that forms the seal between the lid and the enclosure.
Delrin Injection Molding
Injection-molded Delrin, or Polyoxymethylene (POM), is a high-performance thermoplastic renowned for its strength, durability, and adaptability. Its dimensional stability, resistance to creep and warping, and low moisture absorption make it an ideal choice for parts subjected to harsh environments or heavy wear. Additionally, Delrin’s chemical resistance to fuels and solvents enhances its utility across industries. With compliance in its natural grade to FDA, NSF, and USDA standards, Delrin is suitable for applications requiring strict regulatory adherence.
Key Applications of Delrin Injection Molding
Delrin has transformed industries by replacing materials like zinc, brass, aluminum, and steel with its superior performance and cost-efficiency. In automotive applications, its rigidity and wear resistance ensure durable components like camshafts and connecting rods. In electronics, its insulative properties make it essential for casings and packaging. In healthcare, its biocompatibility and corrosion resistance make it ideal for prosthetics and artificial joints. Delrin’s versatility and reliability cement its status as a top choice for injection molding across sectors.
Can Delrin Be Injection Molded?
Yes, Delrin is an excellent choice for injection molding. Its low friction, high tensile strength, and exceptional dimensional stability make it perfect for creating precise parts like gears, bearings, and medical instruments.
The process is carefully controlled, with temperatures 30–60°C (86–140°F) above Delrin’s melting point to ensure proper flow and minimal shrinkage. This results in durable, high-performance components used across various industries, including automotive, healthcare, and electronics.
