The simplest, most robust injection molding method. Utilizes extremely high pressures to force materials into a mold's cavity. The default for any part unless issues demand review of other options.

Gas Assist Injection Molding technology utilizes the injection of high pressure nitrogen gas into the molten plastic toward the final phases of the molding process. This nitrogen produces coring of the thick sections of the plastic part by displacing the molten material as the nitrogen enters the mold. Results are maximized with proper part designs for the particular application.

Advantages:
• Less material
• Shorter Cycle Time
• More Strength
• Improved quality
• Eliminates undercuts
• Permits part consolidation
• Heavier ribs and bosses are possible
• Allows structural tubular sections
• Removes sink marks
• More Design Options

<<   Project Example  >>

Unlike conventional straight injection molding, which utilizes extremely high pressures to force materials into a mold's cavity, structural foam molding takes advantage of a part's configuration (the generally thick wall sections), and the foaming action (supplied by a chemical reaction within the resin blend), to allow the molten resin to flow further, and with lower pressure, than the conventional straight injection molding process would allow.

<<   Project Example  >>

This process allows for "inserts" to be placed into the mold, prior to the molding process for various design implications. This can be metal hardware or other plastic parts. The injection process fills the mold cavities and encapsulates the "inserts" into the part design. This allows for assemblies that would be difficult or impossible to manufacture otherwise.

<<   Project Example  >>

The overmolding process is similar to the Insert Molding process. In this process a thermoplastic material is molded on top of another plastic part. The "insert" in this case is plastic part. This allows for an injection molded part to have (2) or more materials in the same part. The parts can have a mechanical or chemical bond to each other, depending on the resin types selected. Ergonomics have pushed this process and allow for parts to have a hard substrate for rigidity, yet be covered with a softer material for the interface portion of the product.

We own our internal thermoplastic resin compounding operation in Houston Texas.  This is designed to support both internal and external plastic requirements.  Our core competencies include Polypropylenes, Polyethylenes and Polystyrenes.  Other materials are addressed on a case by case occurrence based on overall resin volume and type.   Moving customers to our certified material options is another avenue that way we can bring value to the supply base that others cannot.

Fortis has a fully integrated operation from concept to delivery for both Custom and Standard Profile Extrusions.  We use exacting in house tooling manufacturing capability, co-extrusion, online electronic monitoring and a large variety of materials to meet our customer’s demanding needs for high quality, cost effective plastic solutions.

Our facility utilizes the latest in robotic painting capability by incorporating three Fanuc 6 Axis Painting Robots integrated into a Power and Free computerized conveyor system for the accurate, economical application of Prime, Smooth and Texture Coats of various paints.

We apply EMI/RFI (Electromagnetic Interference / Radio Frequency Interference) coatings to a wide variety of substrates. These applications require great care and experience to ensure proper coverage and protection of internal equipment. In addition many of these applications require precision built masking equipment that we can provide to you.

Our facility as developed a unique internal engineering solution to solve some of the common problems of ultrasonic inserting of treaded studs into the plastic parts. We engineered the combined capabilities of the CNC Machining Center with that of an Ultrasonic Welder to give greatly improved ACCURACY and PRODUCTIVITY to the inserting process. This ensures our customers the most economical, yet most precise insert installation process possible.

<<   Project Example  >>

Manual Ultrasonic insert installation is still a part of our normal operations for those parts that cannot be easily converted to utilize our custom CNC Sonic machinery that we have developed internally. This operation is also good for prototypes and very small run quantities due to the extreme ease of set up.

<<   Project Example  >>

On some particular part designs, it is more beneficial to use heat only instead of ultrasonic energy to bond the plastic materials. We have experience in utilizing this older technology and understand where the correct application for each technology is needed. Sonic Welding and/or Heat Staking can be used to bond similar materials for a permanent assembly or tab features can be "welded" over dissimilar materials to create mechanical bonds.

<<   Project Example  >>

There are several methods to add detail to plastic parts after the molding process is completed. Pad Printing is a relatively easy process of applying ink to plastic or painted plastic parts in our applications. We require artwork to be provided, or we must design internally for the application. This artwork is used to make a plate to transfer ink onto the pad and then onto the plastic part. This is much more economical than "stickers" and the inks come in a large variety of formulas to fit the appropriate application. We also provide Hot Stamping and Silk Screening services to our customers.

Inventory Costs are an important financial consideration for any business. We have increased our value to our customer base by increasing our ability to store product and ship monthly, weekly, or even daily as needed by our customer base to support their JIT inventory systems. We take pride in providing the flexibility needed to give our customers the best value possible.

If you don't want to carry ANY inventory, we have the solution for you! Our flexibility in customer service has allowed us to provide programs that let our customers ship their product DIRECTLY to their end user without ever seeing our customers' facility. This is done by first ensuring the HIGHEST LEVEL OF QUALITY possible on the product to give our customer's confidence that their reputation is in good hands when their customer open product shipped directly from us. This can dramatically reduce our customer's needs for warehouse space and free up valuable working capital for other ventures.

As an international supplier of plastic product, we all well versed in the paperwork and contacts required for shipment outside of the United States. We service customers in North America, Europe and Asia with shipments that range from standard ocean container shipments to expedited international air freight shipments.

Yet another way for us to add value for our customers is a Consignment Inventory Program. With the appropriate agreements in place, we can provide our customers with an inventory program that maintains the inventory at their facilities in a consignment status. This allows for single invoicing per month and lower working capital cost for our customers. The keys behind this program are accurate inventory systems at our customer facilities and the appropriate legal agreements to cover all aspects of inventory cost.
