Laszeray manufactures a wide range of custom plastic injection molded components from nearly any type of engineered resin plastics. Our custom plastic injection molding equipment is capable of processing more than 250 different materials. As a top company, our facility and staff can handle any job, from low-volume short runs to high-volume runs of consumer products that number in the millions of units. Laszeray’s precision systems can create plastic parts in a broad spectrum of sizes and degrees of complexity. We have expertise in manufacturing appearance parts and molding of Eastman Tritan™ co-polyester. We’re one of the most versatile custom plastic parts manufacturers active today.

Quality Molded Plastic Part Manufacturing

Our highly automated plastic molding manufacturing equipment utilizes robotic part handling, trimming, and pad printing to ensure quality and consistency. Secondary operations that include ultrasonic or spin welding, labeling, and kitting are added value services we offer to our customers.

We focus on client relationships and quality production. Our state-of-the-art manufacturing facility houses not only precision injection molding presses, but also an in-house tool shop for production and ongoing maintenance of molds. We have a fully staffed engineering team to conceive and produce top-quality designs, manufacturing capabilities to develop OEM product, and warehouse storage space to maintain customer inventory.

As part of our desire to be first and foremost among custom plastic mold manufacturers, we’re always willing to hear from our customers. Feel free to contact us for more information on our manufacturing services.


Injection Molding Presses – 65 through 1000 ton

Injection-molded plastic parts and products can have many different surface finishes, all of which contribute to making your finished product exactly as designed. Watch this video for a rundown of the choices and uses of texture available for custom molded plastic parts. For more information, contact Laszeray’s design engineers. Our plastic custom injection molding specialists are here to help guide you through this process and much more.

Multi-Shot Molding in 240, 730, & 1000 ton

The two- or three-shot injection molding process is relatively simple. One material is injected into a mold to make the initial section of the product, followed by a second or even third injection of different materials that are compatible with the original material. One machine cycle reduces the number of required product runs while allowing for larger quantities, consequently decreasing labor required to mold parts. It ensures strong bonds between materials without the need for further assembly, resulting in improved aesthetics, ergonomics, and durability. It’s an efficient, cost-effective process that results in higher quality and greater product versatility.

Insert Molding

Insert molding incorporates highly advanced equipment to develop innovative, complex products through the process of molding or forming plastic parts around other, non-plastic parts or inserts. The inserted component is most commonly a simple metal object; however, non-metal materials can also be utilized. This process also allows for flexibility in various markets and incorporates partner technology to produce accurately designed plastic parts.

Robotic Part Handling

Robotic part handling involves putting parts through an assembly process and the transferring, feeding, or removing of parts or tools from machines. End-users utilize robots to improve throughput, quality, flexibility, and consistency while eliminating employees from potentially hazardous jobs. Robotic part handling helps in quick changeovers from one product to the next, can handle a high mix of products, and adjust to throughput demands. Robot technologies are increasing for optimum precision and production during the manufacturing process.

Automated/Robotic Part Trimming

Automated/robotic part trimming is a material separation process that takes place when a router bit, attached to a high-speed automated routing spindle (on the end of the robot), is driven into a part and robotic router head. Then it is guided along the area to be trimmed with clean edges to a predetermined depth. Part trimming delivers flexibility, productivity, safety, quality, and cost-competitiveness to enhance production results considerably.


Overmolding is a process that combines two or more molded plastic or elastomer parts into a single finished product. In the overmolding process, the base layer gets molded first, and then the additional plastic layers are molded over and around the original part. It creates customizable solutions to perfectly match the unique mold design specs and particular needs of the overmolding project.
