Plastic Rods

Plastic Rods- High-Performance Materials for Industrial & Custom Applications

Plastic rods are utilized in countless manufacturing, machining, and fabrication processes across multiple industries. Plastic rods are lighter, resistant to chemicals, and are machinable, so they are a good alternative to metal, wood, or ceramic materials. Whether you are designing mechanical parts, voraciously creating prototypes, or custom fabricating parts, the strength, precision, and adaptability of plastic rods will allow you to deliver high-performance solutions.

Welch Plastics is a reputable plastic manufacturer based in Las Vegas that specializes in custom plastic fabrication. We offer a broad selection of plastic rods in hundreds of materials, sizes, and finishes. With over 20 years of experience in plastic manufacturing and injection molding, we can significantly assist any business or engineer in sourcing or procuring the right plastic rod for all applications.

In this guide, we will cover a range of information on plastic rods, including types of materials, key benefits of using rods, common applications of plastic rods, and how to choose the best rod for your next project.

What Are Plastic Rods?

Plastic rods are solid cylindrical bars made from thermoplastic or thermosetting polymers. Their manufacturing method depends on the type of material and requirements for end use. Plastic rods can be made in sizes from 1/8" to over 12" in diameter, with length being standard (most often 4’’, 6’’, or 8’’) or fully customizable.

Plastic rods offer a range of advantages, regardless of whether you need rigid or semi-flexible rods. Consider:

• A high strength-to-weight ratio
• Excellent resistance to moisture and chemical substances
• Ability to machine easily by turning, milling, and drilling
• Electrical and thermal insulation properties
• A lower-cost alternative to metals/ ceramics

Types of Plastic Rods:

Welch Plastics has a large variety of performance plastic rods for custom fabrication, structural applications, and precision machining. The following table lists our most popular materials with their respective applications:

Material	New Material Advantages	Typical Applications
Acetal (Delrin, POM)	Very high strength, low friction, excellent machinability	Gears, bearings, bushings, and rollers
Nylon (PA6/66)	Tough, wear-resistant, and high-impact strength	Seals, pulleys, wear strips, and spacers
UHMW-PE	Very low friction, tough, and resistant to abrasion	Conveyor parts, guides, and sliding parts
PTFE (Teflon)	Chemically inert, non-stick, very heat resistant	Gaskets, valves, and medical instruments
Polycarbonate	Clear, impact, and UV stable	Safety guards, light housings, and glazing applications
PVC	Flame retardant, rigid, and resistant to chemicals	Plumbing and electrical insulation
Acrylic (PMMA)	Clear, UV stable, and decorative effect	Displays and rods for signage and lighting
Polypropylene	Chemically inert, light, and fatigue resistant	Laboratory parts and water treatment
HDPE/LDPE	Moisture resistant, food safe, and flexible	Cutting boards, tanks, and pipe fittings

Why Choose Plastic Rods over Metal or Wood?

Whether you’re in aerospace, automotive, retail, or food processing, plastic rods offer key advantages over traditional materials:

1. Lightweight and strong

This provides the customer with a durable product that can significantly reduce weight when compared to metals. As a result, it becomes easier to handle, transport, and install. Consequently, this helps reduce time-movement costs as well. 

2. Chemicals and Moisture Stable

Plastic rods do not have a corrosive environment. Water, salts, acids, and solvents will not affect a plastic rod.

3. Easy to Machine

Plastics like acetal, UHMW, and nylon can easily be machined or CNCed into high-tolerance parts with little wear on the cutting tool.

4. Electrical and Thermal Insulating

Many plastics are both insulating and thermally resistant, making them safer and more reliable for electrical and/or electronic applications.

5. FDA/USDA Approved

Plastic needed for food or drink contact? HDPE, PTFE, and polypropylene rods have all been approved by the FDA and NSF food safety standards.

6. UV and Outdoor Performance

Acrylic and polycarbonates are great outdoor materials thanks to their weather and UV resistance. Therefore, they are the media most commonly used for outdoor signage, displays, and architectural applications.

Use of Plastic Rods in Various Industries

Due to its versatility, plastic rods are used in a number of industries. Plastic rods are utilized in varying ways across many different industries:

🔹Machining OEM Manufacturing

• Custom parts such as rollers, gears, and bearings
• Precision-machined components for automation systems
• High wear applications that use UHMW or acetal.

🔹Structural and Mechanical

• Dowel pins, spacers, and mounting brackets.
• Parts that need resistance to vibration or impact strength.
• Nylon and HDPE are suitable candidates for high-demand applications.

🔹Medical and Laboratory

• Lab stirrers, sample rods, and instrument housings.
• PTFE or polypropylene can be used if chemical or biological resistance is important.

🔹Electrical and Plumbing

• Insulator rods, cable guides, and conduit spacers.
• Non-conductive and corrosion-resistant PVC or polypropylene are good substrates for electrical and plumbing.

🔹Retail Displays and Design

• Acrylic and polycarbonate rods are used for signage, shelving, or accent lighting.
• Legion's acrylic and polycarbonate rods are available in clear, frosted, or colored substrates.

How to Select the Correct Plastic Rod for Your Applications

When selecting the right plastic rod for your project, you will need to consider the physical, mechanical, and environmental requirements of your specific application. Things to consider:

• Load bearing capacity: Do you need high dimensional stability or high impact resistance?
• Machinability: Do you plan to cut, turn, or thread the rod?
• Chemical resistance: Will the rod be in contact with solvents, acids, or cleaning agents?
• Operating temperature: What are the operating temperatures and peak thermal conditions?
• Regulatory requirements: Does the rod need to meet FDA, NSF, or USDA compliance?
• UV/Outdoor exposure: If exposed to sunlight or other outdoor conditions, select UV-stabilized materials to enhance durability.
