• Plastic injection molding: 13 machines ranging from 80 to 220 ton clamping force.
• Shot Capacity: from less than a gram, up to 500 gram per cycle.
• Custom Colors: custom plastic parts according to your specifications.
• Insert molding: which allows for other custom injection components such as threaded brass inserts to be completely integrated into the plastic molded part in cycle.
• Over molding: which uses different component materials and integrates them into a single part, much like what you might see on a toothbrush, where a soft elastomer material is molded onto a rigid handle.
• In mold labelling with robot: which uses a robot to place paper or plastic labels in the mold, enabling to give a high finish, decorated final product.

Quality Control

Quality assurance is an integral part of any company in today’s competitive marketplace, and we take it very seriously. QA at PPS INDUSTRIES is a three-step process:

• A visual inspection is performed by our trained machine operators on every part that is made the moment it comes out of our machine using the parameters and critical dimensions set by you, our customer, to identify any rejects.
• The injection molded parts are then randomly inspected once again by our QA personnel at the machine once every hour, and any rejects are logged.
• Finally, the acceptable parts are boxed, counted, and moved to our quality control department, where they are randomly inspected once again, and the count is verified. The injection molded parts are then ready for shipment.

PPS INDUSTRIES is a plastic injection molding contract manufacturer, and is well known by other custom plastic molding companies as a quality molder. We are a molder with the full capability to work competently with our customers to transform their part design into a finished product, or to provide design assistance to make their concept a reality. We currently service the electronics, automative, cosmetics, communications, stationary and household consumer product industries, and pride ourselves on our precision, prompt product delivery, flexibility, and competitive prices.

Plastic Injection Molding Process

How does it work?

The plastic injection molding process has been around since 1872, and is a process of injecting molten material (typically metal or plastic) into a void or cavity that has been created in a particular shape. In plastics, the raw material comes in pellet form, and can be purchased either pre-colored or in a natural state to be colored by the processor, or molder. The natural material is usually colored with a pellet concentrate that looks much like the base material (resin) but has been formulated with high concentrations of pigment. The color concentrate is typically added to the base resin at a ratio of 25/1, or 4%. The resin is then gravity fed through a hopper into a heated barrel that contains a reciprocating screw that rotates, homogenizing the color and base resin together changing the color. Once the machine cycle is started, the plastic injection molding process begins. The mold closes and the material is injected out of the barrel under very high pressure, typically 15-30,000 psi, via a hydraulic pump through a hole in the mold (sprue hole), down a channel (runner), through the gate, and into the cavity. The mold that houses the cavity has cooling channels drilled into it to transfer the heat away much like an engine block, and the material then cools and re-solidifies. Lastly, the mold (or die) opens and the part is ejected. When the part is ejected out of the mold, the steel required to create any undercut design features of the part that prevent it from being removed straight out of the mold need to be dislodged before it can be ejected. This could be threads, holes, or simply a step in the part that traps steel and prevents a straight ejection.

Biopolymers

PPS INDUSTRIES now offers biopolymers as an alternative option in renewable plastic production. These biopolymer products offer a valuable eco-friendly alternative to conventional plastic in many circumstances.

Product Development Process

Here's how we work:

• You bring your products and ideas to us. We will give a free design evaluation and recommend either "design for manufacturing" expertise at no cost to fine tune your product, or quote a more extensive re-design to get your product ready for manufacturing. If your product's design is complete, all the better and you can skip this step!
• We will provide CAD generation and any prototyping you desire on payment terms to ensure your product meets or exceeds your expectations.
• If you decide to use PPS INDUSTRIES' expertise to build your mold, we will discount the initial investment for your mold, the full amount of your CAD and prototyping costs! Mold inserts are excluded from this rebate.

In addition, as long as the mold remains with us we will maintain the polish and quality of that mold, and make sure you get quality products with dimensional stability till the assured number of molding cycles of the tool.

We ensure that we have optimum design for the following key areas:

• Cavities
• Cores
• Runners
• Parting Line Surfaces
• Ejection
• Water Channels

As you can see, there's never been a better time to choose PPS INDUSTRIES, or a better way to feel confident that you have someone who stands behind their work producing your product! We know that you can only get superior parts from superior tooling. We pride ourselves in the art of creating tooling that will stand the test of time, and deliver consistent parts for many years.

PPS INDUSTRIES is a fully capable molder who works closely with customers to transform their design into a finished product. We service the sports equipment, electronics, automative, cosmetics, communications, stationary and household consumer product sectors and pride ourselves on our precision, prompt products delivery, high quality, and competitive prices.
