Material Variety

Choose from more than 200 materials, commodity and engineering resins. We’ll help you balance performance and price and identify alternative material equivalents to reduce costs.

Mercury Marine is very selective in who they use as suppliers. Companies must meet the high quality standards and flexibility that Mercury Marine requires. Nicolet Plastics has consistently met these criteria.

Nicolet Plastics and Mercury Marine engineering and purchasing departments worked together to redesign and prototype an existing part. Each prototype met all the specialized criteria, and through combined innovation Nicolet Plastics was able to move the part into production. The cost came in very low, allowing Mercury Marine to save money and use a better quality part.

Nicolet Plastics adapts very quickly to change, can do custom work and provides each client with the personal attention they deserve.

The first project I ever worked on with Nicolet Plastics, Inc. was in the mid 80’s, and since then the partnership has only grown stronger. Nicolet is willing to try anything to produce the results the client is looking for.

They are on the cutting edge with tooling, equipment and design capabilities. Their design review team provides excellent input; they are creative solution-finders and are very easy to work with. NPI delivers a timely response on product and a quick turn around on tools.

When challenged with difficult mold designs Nicolet is able to simplify the process, thereby reducing costs. Utilizing their in-house rapid prototype machine allows the toolmaker to better understand how the tool needs to be created. One quality control advantage that Nicolet provides for the customer is their storyboards, which detail the proper measurements and color specifications of each piece. Through this self-certification process, Nicolet offers customers the assurance of knowing that each piece is manufactured to exact specifications. I have come to expect that quality work will always be there. You don’t realize how good Nicolet is until you try to compare quality and price somewhere else.

From the President of the company to the guys in shipping, the folks at Nicolet are host, hardworking and down to earth, some of the best people I’ve ever worked with.

I have been working with Nicolet Plastics for 13 years and have never been disappointed. The people at Nicolet Plastics have a true open door policy, and extreme flexibility. They want to be involved in the entire process of your project so they can truly understand the objectives that need to be fulfilled. In my experience, it is rare to find a plastic injection molding company that has the combination of in-house tooling and molding that they do. The quality produced is phenomenal.

Nicolet Plastics is an outstanding company. They are knowledgeable, easy to work with, provide exceptional customer service, produce high quality parts, provide flexible lead times, are always competitive on price and do precision color matching work."

Nicolet Plastics is a cutting edge company that is always willing to take on a challenge.

Nicolet Plastics Injection Molding Process

Injection Molding Process

Molten plastic material is injected into a mold cavity, where it cools and solidifies to create the desired part. The medical, consumer goods and automotive industries all use injection molding extensively. 

The services provided by custom injection molders are extensive and include design, prototyping, tooling, production, and assembly. They can work with a wide range of materials, including composites, metals, and plastics.  

Custom injection molders have the knowledge and skill to create high-quality parts tailored to their customers’ requirements. 

The following are the principal advantages of injection molding: 

  • Able to create complex shapes 
  • Repeatable and consistent results 
  • Obtain precise tolerances. 
  • Automatability for mass production 
  • Economical for small to medium production runs 
  • Fast turnaround times 
  • Reduced labor costs 
Nicolet Plastics Scientific Molding

Scientific Molding

Scientific molding is a process that can be used to create high-quality products with intricate designs. The process is precise and accurate, making it ideal for creating medical devices and other sensitive products.  

Scientific molding is also relatively quick, making it a cost-effective option for product development. 

The main benefits of the scientific molding process are: 

  • Can produce exact and accurate parts 
  • Ideal for creating products with intricate designs 
  • Relatively quick, making it a cost-effective option for the product development process 
  • Can be automated for mass production 
Nicolet Plastics Overmolding


Overmolding is a part design feature that can be used to improve a product’s function, durability, or aesthetics. In overmolding, one material is molded over another to create a strong bond between the two materials. This can be used to create products with multiple colors or textures or to improve the grip of a handle.  

Overmolding can add strength or flexibility to a part or seal two materials together. A versatile manufacturing technique that can create a wide variety of products. 

The main benefits of overmolding include 

  • Can produce highly intricate designs 
  • Bonds two materials together for a stronger finished product 
  • Can be used to create products with multiple colors or to add a textured finish 
  • Faster production times compared to other manufacturing methods 
Nicolet Plastics Insert Molding

Insert Molding

Insert molding is a type of plastic injection molding part design that creates a three-dimensional part from a two-dimensional shape. The part is created by injecting molten plastic into a mold cavity, where it takes the shape of the cavity. 

Insert molding can create parts with multiple features, such as a knob with a built-in screw thread. It can also make parts with embedded metal or other materials. Insert molding is a versatile manufacturing process that can create a wide variety of parts. 

The main benefits of insert molding are: 

  • Can create small, intricate parts with ease. 
  • The process is versatile and can be used to create a variety of parts. 
  • Parts can have multiple features, such as embedded metal or other materials. 
Nicolet Plastics Part Decorating

Part Decorating and Labeling

There are a variety of ways to decorate and label parts created through custom injection molding. One popular method is to use a laser etching machine to create text or graphics on the part’s surface. This can be used to add branding or other information to the part. Another common method is using a silk screen printer to apply a design to the part’s surface. 

The main benefits of decorating and labeling parts include: 

  • Can add branding or other information to the product 
  • Can create different looks with this product 
  • Quick and easy way to add color or graphics to a product
