Texas Injection Molding Maximizes Building Envelope for Storing Plastic Resin

Texas Injection Molding completed the expansion of it’s new materials warehouse in 2024.  Injection molding facilities handle a constant flow of plastic resin, most often delivered in bulk containers like gaylords or super sacks. Storing and moving these heavy loads safely and efficiently is critical to keeping production lines running smoothly. Texas Injection Molding worked with Crown to efficiently lay out the rack locations and place a magnetic wire in the floor to guide the Crown TSP 6500-33 lift.

Built for Heavy Loads

The TSP 6500-33 is designed to lift and maneuver heavy materials with ease. Most plastic resin is supplied in Gaylords and Supersacks. These bulk containers typically weigh 1,500 to 2,500 pounds. With the Crown lift, operators can safely transport these bulky loads without the risk of spills, damage, or injury.

Efficient Use of Floor Space

The wire guided Turret lift allows for narrow isles providing for significantly more rows.  The Crown lift allows us to utilize all of our 32′ ceiling height with a high pile permit from the City of Houston.

Safety and Stability

The Crown TSP 6500-33 provides excellent stability while lifting and transporting, giving operators confidence that their loads are secure. The magnetic wire guidance system ensures that the lift travels between the narrow isles in the exact position to avoid drifting off course or running into the racking system.  This translates into fewer accidents, less product loss, and a smoother workflow overall.

Long-Term Value

Because it is built to handle demanding industrial applications, the Crown TSP 6500-33 provides durability that injection molding companies can rely on. Texas Injection Molding operates 24 hours a day and pushes the equipment hard.  Fork lifts are a critical piece of equipment to our operation and any downtime causes significant disruption. Investing in equipment that supports both safety and productivity makes a noticeable difference in the bottom line.

How It’s Made: Manufacturing Over Molded Pistol Grips

How It’s Made: A Two-Step Approach to Over Molded Pistol Grips

Creating a pistol-style grip that exudes both ergonomic comfort and durability involves a precise two-step over molding process. By injecting molded PA66 base parts and over-molding with a thermoplastic urethane (TPU) cover, manufacturers can achieve a perfect balance of stability and resilience that serves end-users well. Texas Injection Molding stands out in this domain with its practical expertise in producing high-quality, lower volume products that meet stringent specifications.

Step One: Injection Molding the PA66 Base Part

The process begins with the injection molding of a PA66 base part. Polyamide 66 (PA66) is selected for its advantageous properties, especially its strength and thermal resistance, making it ideal for the structural demands of pistol grips. Injection molding of PA66 allows for precise formation, ensuring consistent quality and tight tolerances essential for the grip’s foundation. During this stage, maintaining control over parameters such as temperature, pressure, and cooling time is crucial to prevent defects and ensure the integrity of the base part.

Step Two: Thermoplastic Urethane Overmolding

Once the PA66 base is molded, the next step involves over-molding with thermoplastic urethane. TPU is preferred for its outstanding flexibility, soft touch, and impact resistance—qualities that enhance user comfort and grip security. During this stage, aligning the TPU seamlessly with the pre-formed base part requires expertise in managing material compatibility and adhesion integrity. The ability to achieve a smooth interface without compromising the grip’s ergonomic design is where skilled over-molding techniques prove invaluable.

What sets this process apart is not only the mechanical bond but the tactile quality it delivers. The combination of PA66 and TPU offers a functional and aesthetic benefit that meets the demands of professionals and hobbyists alike.

By deploying this two-step manufacturing process, while leveraging insights from seasoned practitioners in the field, businesses can confidently produce pistol-style grips that meet specific use-case requirements efficiently. This method ensures that each grip is a genuine reflection of engineering precision and user-centric design.

For those in search of manufacturing solutions that reflect both quality and practicality, adopting this two-step method presents an efficient path forward. It’s this commitment to excellence that makes Texas Injection Molding a valued partner in navigating the intricacies of over-molded product creation.
