Plastic Molding Services for Agricultural Applications

Hi-Rel Plastics manufactures durable plastic components for agricultural and farming equipment, supporting everything from part evaluation and prototyping to tooling, production, and secondary operations. Our team works with rugged materials and functional designs to meet the demands of agricultural environments.

Built for Harsh Outdoor Conditions

Agricultural equipment and systems require durable, high-performance components capable of withstanding harsh outdoor environments, heavy use, and continuous exposure to moisture, chemicals, UV radiation, and extreme temperatures. Hi-Rel Plastics produces precision-molded plastic parts designed to deliver long-term reliability and consistent performance. With experience in engineering-grade resins and quality-focused manufacturing, we help agricultural equipment manufacturers and OEMs develop components that balance strength, durability, and cost efficiency while meeting production and functional requirements.

Below are some agriculture industry applications of molded plastic components:

Injection Molding

  • Irrigation valve bodies and water distribution fittings used in drip and sprinkler
    systems
  • Sensor and control housings for agricultural machinery monitoring soil, moisture,
    and equipment performance
