Customized design and a full range of plastic material material offerings including a wide variety of colorant and over-molding options.

Custom plastic injection molders employ computer-aided design (CAD) software or similar to produce custom molds machined with different disciplines out of solid metal and generally have two halves that will come together during the mold assembly process.

As a reputable plastic injection molding company, we offer an array of materials that can be used in the production process. Learn more about various materials that we use at our materials page.

During and after the injection molding, and before shipping the components to the client, the parts go through a thorough quality inspection.

During the process of plastic molding manufacturing, a molten plastic mixture is forced under high pressure into a custom-made mold so that the material takes the shape of the mold cavity. Once the part has been removed from the mold it is typically finished, but may require secondary operations.

American inventors and the first plastic injection molding manufacturers, brothers Isaiah and John Wesley Hyatt patented the very first injection molding machine in 1872. Despite its seemingly simple original design, this machine made the manufacturing process infinitely easier. It also served as the prototype for the sophisticated machines that we use nowadays, since the principle is much the same to this day.

A mold life expectancy can last between hundreds and millions of parts if properly constructed and maintained. The application (i.e. prototyping, production) usually dictates the mold’s endurance.

Advanced precision ceramic & plastic molding enable us to deliver high quality, cost-effective parts every single time and for a wide range of clients operating in specialized industries.

The life of an injection mold is directly related to the type of mold, the type of material injected into it, and the number of parts produced.

A plastic injection company is a business that handles plastic molding manufacturing. Typically, these companies operate on a medium to large scale, producing large quantities of plastic molds and related products for a diverse range of applications.If you’re looking for one of the best plastic injection molding companies, we’re here to help you with our expertise and precision.

Special varieties of plastic are typically used in the injection mold manufacture, including: polycarbonate, acrylonitrile butadiene styrene (ABS), nylon, etc.

Carefully selected resin pellets undergo the melting process, injecting them into the mold cavity, and left to cool and solidify.

There are many benefits to using injection molding over other manufacturing methods to produce plastic components. For example:

While injection molding offers a number of advantages over other manufacturing methods, it also comes with some challenges, such as:

The process of manufacturing plastic injection molding is ideal for producing large quantities of identical objects due to the following key advantages:

Polycarbonate (PC) is generally considered to be the top plastic for injection molding when it comes to sheer durability. This material boasts excellent impact resistance and high tensile strength, making it suitable for a wide range of applications, such as car parts, medical devices, and even electronics.

The plastic injection molding process involves heating plastic (in pellet or grain form) until it has melted. The molten material is then injected into a closed two-part mold under high pressure, where it cools and solidifies. Once the material has fully hardened, it maintains the shape of the mold cavity. At this point, the mold can be opened so the piece can be removed and sent for further processing as needed.

Many industries use injection molding to produce their parts and products. The process enables them to create components of various shapes and sizes in high quantities (i.e., thousands or millions of pieces) quickly, consistently, and cost-effectively. While it can be used with a variety of other materials (e.g., glass, metal, and rubber), it is most commonly utilized for plastic. For example, clear plastic is often injection molded to form personal protective equipment (PPE), such as face shields and goggles, for industry professionals.

Since injection molding represents the most common method of plastic parts manufacturing, the list of products can range from bottle caps to car parts. More complex parts are made out of a combination of two or more materials through a special process called overmolding.

Capable project management from design to final part. One-stop service for all of our clients’ plastic injection molding.

Yes, plastic injection molding typically produces parts that are much stronger than their 3D-printed counterparts. These are the reasons why:
