Plastic Molding Companies
Plastic processes differ greatly in both the way they form plastic products and in the shape and structural integrity of the products they manufacture. Blow molding, for example, is nearly the sole method by which plastic bottles for beverages, household cleaners and cosmetic products are made, as well as a range of low-cost toys and parts with low to medium performance. The extrusion process creates linear profiles, strips and sheets with high structural integrity useful in many construction siding, trim and furniture applications. Vacuum forming, or thermoforming, forms trays, linings and thin plastic packaging from heated plastic sheets, while dip molding forms a variety of soft molds and plastic coatings. Other plastic molding processes use casts, or dies; injection molding squeezes melted (or “plasticized”) plastic resin into a closed mold, forming a solid plastic object, while rotational molding uses a type of gyroscope to evenly coat the inside of a mold, creating hollow parts with high impact resistance. Plastic molding processes vary greatly in cost. High end plastic molding processes, such as rotational molding and injection molding, provide precision three dimensional plastic parts with structural integrity and impact resistance few other processes or materials can provide. On the other end of the spectrum, blow molding and dip molding processes offer very affordable options for long runs and mass production of containers and household commodity items. A wide range of plastic materials are molded through these processes, although some processes are more effective with certain polymers than others.
Types of Plastic Molding:
Fiberglass fabrication is the process of combining thin glass fibers with different resins to produce a strong, light weight product. Since the introduction of fiberglass, it has been used as a reinforcing agent for plastics as well as insulation in buildings and appliances. Fiberglass is used in fabrication applications that demand light-weight material with high-strength and scratch-resistant qualities.

This is one of the most common forms of plastic molding, and the process can range widely in cost, depending on the complexity of the part being molded and the materials which are used. Injection molding produces three dimensional, solid parts with mid to high strength and is unique in plastic molding processes, as it can produce relatively complex shapes. Advanced injection molding techniques include insert molding and reaction injection molding (RIM); insert molding dies contain a solid object, such as an electric coil, around which the molten plastic is injected, creating an encapsulated object. Reaction injection molding combines a liquid resin thermoset polymer (typically polyurethane) with liquid polyisocyanate, which acts as a reagent within the mold, causing the polymers to expand and form bubbles (either open or closed cell foam), filling the mold.
Injection molding machines consist of three main sections: the hopper, where plastic resin pellets are fed into the machines; the extruding barrel, containing a small screw conveyor which simultaneously “plasticizes”, or melts, the plastic resin while moving it towards the die; and the die, or closed mold, into which the melted plastic is injected under pressure. The plasticizing of the resin is often assisted by electric band heaters and cartridge heaters wrapped around the extruding barrel.

Plastic extrusions are formed similarly to the way injection molded plastics are formed, although extrusions are formed through an open die. Plastic resins such as PVC, acrylic, polypropylene or ABS are fed through a hopper into the extruding barrel, which shears and melts the resin, pushing it through the open die to form a profile or shape. This profile is immediately immersed in cold water to set the plastic; the profile is extruded continuously, passing through the die, through cold water tanks and onto a sawing table, where pre-specified lengths are cut.
Extruded plastics may be manufactured to meet the specifications for a broad range of niche applications, including but not limited to building trim, window and door sealants, vinyl siding, PVC pipe and surgical tubing. Plastic sheets and flexible plastic sheet rolls are also formed through extrusion, being pulled and stretched instead of cooled after the melted plastic exits the die; flexible plastic sheets are rolled through a series of large calenders before being rolled onto a tube.

Dip molding plastic is one of the simplest means of molding plastic and, like blow molding, is capable of producing a large number of parts or products at low cost. The dip molding process serves in one of two manufacturing capacities: to create whole flexible or rigid products such as rubber gloves, condoms and plastic caps; or to coat pre-manufactured products such as wire racks, wire cable and plastic coated handles.
Both manufacturing methods use the same basic process: a large volume of glass or metal molds are surface prepped, so that the final product may be easily stripped from the mold when dry. Objects which are to be coated in plastic are buffed and prepped so that the plastic coating stays firmly on. The molds are then dipped into a vat of molten polymer or elastomer resin; depending on the desired thickness and the consistency of the polymer material being used, molds are often dipped multiple times, sometimes alternating between cold water or another solidifying reagent and the molten polymer vat. Flexible products with complex layers, such as kitchen gloves, may have other layers, such as a fabric layer, applied in between polymer coats. Once the molten plastic has set, the plastic product is ready to be removed from the mold, trimmed, cleaned and finished.

Plastic molding is the process of using molten plastic or polymer resin to create molded plastic products for a variety of commercial and industrial uses. It is the most common manufacturing technique employed in the making of objects we use each day, ranging from automotive dashboards to bottle caps and children's toys. Plastic has become a popular alternative to metals, wood and glass as its wide range of properties are able to suit many different applications.
Plastic polymers, in the form of thermoplastics, thermosets and elastomers, are a popular manufacturing material because of plastic's durability and malleability. The process of plastic molding is used for mass production and prototyping because of its ability to yield high runs at close tolerances. Plastic molding typically involves a pre-made mold and liquid plastics; however other manufacturing methods include vacuum forming, injection molding, blow molding and compression molding. The type of molding process chosen usually depends on the final intended use of the product being made, and the process is commonly used in the consumer, food service, medical, plumbing, computer and automotive industries.

Rotational plastic molding is capable of achieving plastic parts with more strength and structural complexity than any other plastic molding processes. Unlike other plastic molding methods, rotational molding produces a relatively low volume of parts in what are typically short runs, due to the amount of time and equipment required for rotational molding. Rotationally molded plastics may not be mass produced like blow molded, dip molded or thermoformed parts, and this process is typically reserved for complex or high-performance parts such as plastic figurines and military-spec rackmount carrying cases.
The rotational molding process is unique among plastic molding techniques. A molten polymer – often polyethylene or polycarbonate – is poured into a closed three dimensional mold; the mold is then placed within a gyroscope-like structure which slowly spins, evenly coating the entire interior of the mold with the polymer to form a hollow shape. This process is not only more effective at creating complex three dimensional structures, but it also creates parts with uniform material consistency and, consequently, very high strength.

Vacuum formed plastics are used as faceplates and semi-flat components in a wide range of industries, particularly in electronic equipment such as fax machines, keyboards, phones and home appliances. Also known as thermoforming, or pressure forming, the vacuum forming process begins with stock plastic sheets rather than polymer resin pellets; these sheets are heated until the polymer reaches a flexible temperature, then they are vacuumed into an open mold, causing the heated sheets to “thermoform” to the exact shape of the die mold beneath. Twin sheet thermoforming is commonly used to create large and precision application parts such as hot tubs and interior wall panels for aerospace, but thermoforming is also a highly cost-effective means of producing three-dimensional plastic packaging. Blister packs, clamshells, plastic covers, plastic trays and other plastic packaging can be produced for low costs at high runs by vacuum forming.
