Custom Thermoforming From Concept to Repeat Production
Developing a new product, improving an existing design, transferring a program, or replacing a metal component with plastic? Our team can support the process from early engineering through repeat production.
With our complete set of thermoforming plastic services, including heavy-gauge thermoforming, custom sheet extrusion, CNC trimming, finishing, assembly, and inventory support, we offer a smoother path from prototype to finished part.

Heavy-Gauge Thermoforming
Our 20+ thermoforming machines support single-sheet forming, twin-sheet forming, drape forming, pressure forming, and sheet-over-sheet forming. We produce custom plastic components up to 8 feet by 14 feet by 60 inches using material from .060 to .55 inches thick.
Engineering and Design Support
Our IDEA Center gives you access to experienced engineers and designers who understand plastic materials, tooling, forming, trimming, and production. We work with your team to improve manufacturability, performance, quality, and cost before production begins.


Custom Plastic Sheet Extrusion
We extrude custom thermoplastic sheet in a wide range of materials, colors, textures, and thicknesses. In-house extrusion gives you greater control over material performance and helps simplify the transition from sheet production to thermoforming.
Prototyping and Thermoform Tooling
We support prototype development and custom thermoform tooling for new products, transferred programs, and part improvements. Our team works with you to evaluate part geometry, material requirements, production volumes, and long-term performance so the tooling is designed for consistent, repeatable production.


CNC Trimming and Plastic Finishing
Our CNC and robotic trimming equipment helps us produce clean, consistent results across complex thermoformed parts. We can also complete die cutting, punching, finishing, hardware installation, and bonding, reducing the amount of secondary work you need to coordinate elsewhere.
From Finished Part to Production-Ready Delivery
We help take the work off your plate after production. From assembly and kitting to inventory management, JIT stocking, packaging, labeling, and fulfillment, we prepare your products for the next step in your operation or supply chain. With flexible storage and delivery support, you can reduce internal handling, keep inventory moving, and receive the right products in the right quantities when you need them.
Thermoformed Plastic Solutions for Demanding Applications
Whether you are looking to reduce weight, improve corrosion resistance, protect sensitive products, simplify handling, or create a more repeatable production solution, our team brings years of experience solving these types of complex challenges.
Across the agriculture, automotive, medical, construction, lawn and garden, transportation, and industrial markets, we help customers improve structural strength, appearance, handling, environmental exposure, and production consistency. The end result is a thermoformed plastic solution designed to deliver the performance your product and application require.
Agriculture
Weather-resistant housings, panels, covers, bins, and other thermoformed assemblies for agricultural equipment and outdoor applications.
Automotive
Interior, exterior, protective, and material handling products designed around automotive quality, appearance, and production requirements.
Transportation
Large-format plastic parts, reusable packaging, crates, and protective solutions for transportation and mobility applications.
Packaging & Dunnage
Custom reusable packaging, thermoformed dunnage, trays, inserts, cradles, and protective components designed to secure products throughout manufacturing, storage, and transportation.
Medical
Custom thermoformed parts, trays, housings, and packaging solutions for medical and healthcare related equipment.
Construction
Durable plastic parts designed for demanding environments, outdoor exposure, and repeated use.
Lawn and Garden
Storage products, plant trays, equipment components, covers, and other custom plastic products.
Industrial
Heavy gauge thermoformed parts, enclosures, guards, housings, trays, and material handling solutions for industrial equipment and production environments.
Material Handling Solutions
Reusable Packaging Designed Around Your Product
Standard packaging does not always provide the protection, efficiency, or durability your supply chain requires. When you are looking to prevent damage, improve handling, maximize trailer or storage space, reduce disposable materials, and support returnable logistics programs, custom packaging remains a proven solution.
At Allied Plastics, we have years of experience designing and manufacturing custom thermoformed material handling solutions for repeated use throughout manufacturing, storage, and transportation.
These solutions commonly include:
- Reusable plastic packaging
- Thermoformed trays
- Sleeve packs
- Wheel packs
- Rackable pallets
- Bulk packaging
- Lightweight packaging
- Heavy-duty industrial packaging
- Custom cradles and protective components
The Allied Plastics Advantage
Allied Plastics combines experienced people with the equipment, facility space, and production capabilities needed to support demanding manufacturing programs. Many of our senior team members bring more than 30 years of thermoforming experience, giving customers access to a team that understands the technical, quality, and production requirements behind complex plastic parts and packaging solutions.
Our Twin Lakes facility houses some of the largest plastic thermoforming machines in the country, along with the in-house capabilities needed to provide integrated thermoforming plastic services. By bringing our services together, we can help simplify your program, reduce handoffs, and maintain greater control from design through delivery.
