Industrial Plastic Manufacturing Capabilities
Diversified Plastics Industrial Solutions is a USA manufacturer with 50 years of experience in injection molded UHMW-PE, cast urethane, CNC machining, thermoforming, and custom fabrication. Whether you’re replacing a metal component or scaling from prototype to production, all capabilities are under one roof. Cost savings are proven by our ability to serve as a single-source vendor, regardless of the application, material, or required volume.
INJECTION MOLDED UHMW (UHMW-PE)
Injection molded UHMW-PE is built for demanding wear applications where low friction and durability matter. It offers abrasion resistance and corrosion/chemical resistance while remaining lightweight. It’s also a cost-efficient alternative to many machined plastic components.
- Best for: Wear components and metal-replacement applications
- Benefits: Wear resistant, low friction/self-lubricating, cost-efficient vs. machining
- Options: Mold-in IDs/colors/dates, mold around inserts, overmolding with elastomers
INJECTION MOLDING
From prototype to production, injection molding supports consistent, repeatable part manufacturing at scale. In-house tool design and mold fabrication help streamline the path from concept to finished parts. Machine capacity ranges from 19 oz to 311 oz shot sizes.
- Range: 19 oz to 311 oz shot sizes
- Materials: UHMW-PE, nylon, acetal, urethane, Ultem, PEEK, HDPE, polypropylene + filled materials
- Value: Converts high-cost machined parts to scalable molded production
CNC MACHINING
When specifications are strict and tolerances are tight, CNC machining delivers precision plastic components. This capability supports parts that require exact dimensions and dependable repeatability. It’s a strong fit for engineered plastics and detailed geometries.
- Best for: Tight-tolerance parts and exacting requirements
- Capabilities: CNC milling, turning, routing + cutting/drilling/forming support
- Equipment: Broad CNC capacity including HAAS machines (as listed)
CAST URETHANE
Cast urethane is a versatile option when hardness and performance need to be tailored to the application. Components can be cast into custom shapes, poured into plates, or bonded to rolls and wheels. Durometers range from 40A to 75D.
- Hardness: 40A to 75D durometer
- Uses: Rolls, wheels, plates, and custom cast shapes
- Control: Hardness and performance tailored to your requirements
CUSTOM FABRICATION
Custom fabrication supports complex parts and assemblies across materials ranging from plastics to metals. A cross-trained team and 3D fabrication workflows help tackle unique builds and multi-step projects. It’s an ideal option when parts need more than a single process.
- Capabilities: Multi-process fabrication under one roof
- Team: Cross-trained fabricators + 3D workflows
- Equipment: Fabrication equipment and CNC resources (as listed)
OVERMOLDING / INSERT MOLDING
When one material can’t do it all, overmolding and insert molding combine materials into a single finished component. This approach can improve grip, durability, and impact absorption while simplifying assembly. It also helps place metal strength only where it’s needed, such as threads, shafts, or bearings.
- Best for: Grip layers, impact damping, wear surfaces, integrated strength
- Advantages: Fewer fasteners, simplified assemblies, targeted metal where needed
- Materials/Inserts: UHMW, TPE/TPU, nylon, polypropylene, urethanes + metal inserts/bearings/shafts
THERMOFORMING
Thermoforming is a cost-effective way to shape plastic sheet using heat and pressure. It’s a strong fit for low-volume production or short runs where low set-up and tooling costs matter. Equipment includes vacuum forming up to 3’ x 4’ and heat-forming ovens up to 5’ x 12’.
- Why: Low set-up and tooling cost
- Equipment: Vacuum forming up to 3’ x 4’; ovens up to 5’ x 12’
- Options: Sheet bending up to 10’ + welding/bonding methods (as listed)
Frequently Asked Questions
Injection molding is more cost-effective for medium-to-high volume production because tooling costs are offset over many parts. CNC machining is better suited for tight-tolerance, low-volume, or prototype parts where custom tooling isn’t justified. DPI offers both, which means we can recommend the right approach based on your volume, geometry, and budget.
Cast urethane is a strong choice when hardness needs to be tailored to the application, or when you need custom shapes like rolls, wheels, or plates without the upfront cost of injection molds. It’s also well-suited for parts requiring a specific durometer — DPI can cast urethane from 40A to 75D.
DPI serves a wide range of industries including lumber and forest products, water and wastewater treatment, food processing, mining, agriculture, egg processing, conveying and packaging, oil and gas, and car wash equipment.
Modern industrial plastics offer a combination of benefits that metal often can’t match in wear applications: lighter weight, corrosion and chemical resistance, lower friction, longer wear life, and in many cases lower total cost. Plastic components also don’t rust, which matters in environments like water/wastewater treatment, food processing, and outdoor equipment.
The best way is to get DPI’s team to evaluate it. We offer no-cost facility visits specifically to assess current parts and identify plastic conversion opportunities. Material properties like abrasion resistance, load-bearing requirements, and operating environment are all factors in that evaluation.
DPI has an in-house engineering team with experience across materials and manufacturing disciplines. They can help with part design, material selection, design for manufacturability, and prototype tooling — all under one roof.
