Manufacturing Capabilities

A plastic extrusion house is only as good as its capabilities. During our more than 40 years in the plastics business, we have continued to develop and deliver innovative extruded plastic solutions that have solved problems for hundreds of leading companies in various industries. We offer a variety of different manufacturing capabilities to meet your needs, including coextrusion, fabrication and hollow tubing. We have solid partnerships with companies that provide injection molding services and more. We can do everything from simple punching and notching to complex plastics engineering. Our extensive experience in the plastics industry enables us to assist you in the design and creation of the essential elements you need to build your products.

Within our facilities, we design and build the tools, machines, and equipment to perform tasks such as lamination, tight tolerance cutoffs, and intricate secondary operations. Our thermoplastic extrusion equipment and technicians are second to none in the industry, and we are always pushing the envelope to identify, evaluate, and implement state-of-the-art techniques and processes to use in extruding plastic profiles. Our two machine shops provide our customers with extremely fast turnaround times.

We can deliver the following capabilities with extruded plastic profiles:

  • Coextrusion
  • Fabrication
  • Embossing/Lamination
  • Color Matching
  • Injection Molding

Plastic Manufacturing FAQs:

For over 40 years, Keller Plastic’s expert plastic manufacturers have provided businesses in various industries with high-quality, durable extruded plastic profiles for multiple applications. During our four decades of service as a premier plastic manufacturers company, we’ve noted a few of the most common questions regarding plastic manufacturing. Here are answers to the most frequently asked questions:

Why Is Wall Thickness Important in Plastic Manufacturing?

Wall thickness is a crucial factor for plastic manufacturing for various reasons. First, it affects the strength and durability of the finished product. For example, thin walls are more likely to break or crack under stress, while thick walls can better withstand impact and tension. In addition, wall thickness also affects the aesthetic appearance of the finished product.

Thicker walls may appear bulkier or less streamlined, while thinner walls can give the illusion of being lighter or more delicate. Naturally, wall thickness also impacts the cost of manufacturing. Thinner walls require less material and can be produced more quickly, resulting in lower production costs.

The ideal wall thickness primarily depends on your product’s use or intended purpose. Some products may better function with thinner walls, while others require thicker walls for optimal durability and performance. For these reasons, wall thickness is a critical factor that plastic manufacturers carefully consider.

What Is Plastic Fabrication?

Plastic fabrication is the process of creating objects or structures from plastics which is done through various methods, such as molding, casting, or machining. Fabrication is used in multiple industries, from consumer goods to automotive manufacturing. Its properties make it an ideal material for many applications. It is strong and durable yet lightweight and easy to work with. It can also be molded into any shape, making it versatile and customizable.

What Is Acrylic Plastic?

Acrylic plastics are transparent and lightweight materials with many applications in numerous industries. It is often used as an alternative to glass, as it is shatter-resistant and can be easily molded into various shapes. It is also used in several consumer products, such as:

  • Shower doors
  • Eyeglasses
  • Car tail lights

In addition, acrylic plastic is used for industrial purposes, such as in producing aircraft windows and medical devices. Thanks to its versatility and durability, it has become one of the most popular materials.

Do You Require Plastic Profiles Mated With Injection-Molded Components?

Plastic profiles are often used with injection-molded components, but this is not always the case. In some instances, plastic profiles can be used alone or in combination with other materials. Using its profiles with injection-molded components ultimately depends on the specific application and the desired results. As many companies look to reduce their reliance on single-use plastics, there is an increasing demand for sustainable, eco-friendly alternatives.

One way to achieve this is using plastic profiles mated with injection-molded components. This process allows for the reuse of its waste, which would otherwise end up in landfills. In addition, it helps reduce greenhouse gas emissions and the overall carbon footprint of the manufacturing process. As companies increasingly seek to reduce their environmental impact, plastic profiles mated with injection-molded components offer a viable solution.

What Is High-Density Polyethylene?

High-density polyethylene (HDPE) is a type of plastic commonly used in various applications. It is characterized by its high strength-to-density ratio, making it ideal for products that need to be durable and lightweight. HDPE is also non-toxic and produces very little waste during manufacturing. As a result, it has become one of the most popular plastics on the market. Some common uses for HDPE include food packaging, bottles, containers, pipes, and tubing. It is also often used in construction and industrial applications. Thanks to its versatility and durability, HDPE is a vital plastic material today.

What Is Low-Density Polyethylene?

Low-density polyethylene (LDPE) is a type of plastic commonly used in food packaging, grocery bags, and trash can liners. LDPE is classified as a thermoplastic, meaning it can be melted and reformed multiple times. Unlike other plastics, LDPE is not brittle and is resistant to breaking. LDPE is also less likely to leach chemicals into food or beverages than other types of plastic.

As a result, LDPE is considered a safe and versatile material for food packaging and other consumer products. Despite its many benefits, LDPE does have some drawbacks. It is not as heat-resistant as different types of plastic and can become cloudy or opaque when exposed to sunlight. In addition, LDPE is not recyclable in most curbside recycling programs. However, many municipalities offer special drop-off programs for recycling LDPE products.

How Do I Find Plastic Manufacturers?

You need to ask yourself a few critical questions before finding the right plastic manufacturing company for your product. First, what type are you looking to have manufactured? There are a variety of different plastics on the market, each with its own set of properties and manufacturing processes. Once you know what type of plastic you need, you can narrow your search for manufacturers.

Another critical question is what volume of plastic you need to be produced. Not all manufacturers can produce large volumes, so it’s crucial to know your needs upfront. Finally, you’ll need to consider your budget. Depending on the size and complexity of your order, some manufacturers may be more expensive than others. By asking yourself these key questions, you can start narrowing your search for plastic manufacturers that meet your specific needs.

Determining the end products you want to create also plays a role in deciding which plastic manufacturer is best for you. Does this plastic manufacturer make medical devices? Are they known for only producing automobile parts? Do they only manufacture packaging materials? There are several types of plastics, each with its strengths and weaknesses.

The next step is to choose the processes you will use to create your products. There are two main plastic manufacturing processes: injection molding and extrusion. Injection molding is well suited for creating complex shapes and is used to create products with multiple cavities. Extrusion is best suited for creating long, continuous sheets of material. Once again, the choice of the process will be dictated by the end products you want to create.

There are many different types of plastics, each with its characteristics. It would be best if you chose reliable plastic manufacturers with experience creating plastic profiles similar to your product. In addition, you will need to determine how you will acquire the raw materials you need. There are many different sources for these materials, and you must choose the one best suited for your manufacturing operation.

Though plastic manufacturing has only been in mass production for a little over a century, it has become ubiquitous in our lives. It’s hard to imagine a world without plastic – it’s used in everything from packaging to building materials to consumer goods.
