OMICO Plastics manufactures custom blow-molded plastics for a variety of industries. Blow molding is a manufacturing process that uses two-piece molds to produce hollow objects made of plastic. Different variations of the process include injection blow molding, extrusion blow molding, and stretch blow molding. The processes can be used to meet precise specifications like injection capacities of 0.66 to 25 pounds, sizes ranging from 1 inch to 6 feet, and multi-component fabrication.

Durable products made by blow molding are becoming increasingly critical for the military and defense industry, especially for their prototyping, ammunition, food service, and other needs.

Blow Molding for the Military and Defense Industry

Custom blow molding allows us to meet the specifications for any product. Compressed air during manufacturing allows our technicians to create products without exposure to outside variables. Our 26 different machines allow us to customize products for a variety of applications, including ammunition components, fuel tanks, and any other hollow container.

Plastics & Materials Available

Modern high-quality plastics have many high-performance features that provide essential functional properties like chemical resistance, flexibility, biocompatibility, compressibility, memory, and heat resistance. These properties and precision capabilities make blow-molded plastic products ideal for military and defense applications. The types of plastics and methods used may vary depending on the type and use of the finished product. 

Plastics used in military and defense blow molding may include:

  • ABS
  • Acetal
  • EVA
  • Flexible PVC (TPU blend)
  • K-Resin
  • PETG
  • Polycarbonate
  • Polypropylene
  • Polyethylene (HDPE, LDPE, LLDPE)
  • Santoprene

Blow Molding Applications

The custom blow molding process utilizes a mold and injected air to create hollow products with specific qualities. The process can create products in different sizes for the following applications in military and defense.

Food Service

A variety of plastics can be used to keep food fresh. Custom blow-molded products for food preservation may include water bottles, medication bottles, rigid bins, film packaging, plastic bags, and squeeze bottles.


Precision is crucial in ammunition and firearm part manufacturing. They require top-tier aesthetics, extreme rigidity, high impact strength, tight tolerances, and repeatability. Our blow molding process is capable of creating high-strength plastics and custom specifications.

Fuel Tanks

With properties that offer a longer lifespan than traditional metal options, high-quality plastics make more reliable fuel tanks for all types of vehicles. The blow molding process can create large fuel tanks that are lightweight and moisture-resistant. These qualities eliminate the risk of rust and the burden of added weight to precision military vehicles.

Products Manufactured

Some of the custom blow-molded products we manufacture for military and defense include:

  • Fuel tanks
  • Pistol frames
  • Upper and lower receivers
  • Buttstocks
  • Magazines
  • Grips
  • Projectiles
