Machine Capabilities

16 blow molding machines are available for production service. For a more thorough explanation of machine capabilities, please Contact Us. Machine selection is based on the customer’s product parameters and mold traits. The product and mold are used to determine what head size and tooling will be used on the product and what size clamp will suit the mold. Machines range from 1 to 40 pound shot sizes. As a general guideline, ACM can produce parts within these parameters: 1" to 30” part width, 1" to 60” part length.

Clamp size is the distance between tie bars (width) x maximum clamp opening (daylight).

Materials Used

Common Materials

High Density Polyethylene (HDPE) – ACM's most common plastic offers excellent processing, chemical resistance, impact resistance, and recyclability. ACM uses both natural virgin HDPE and black reprocessed HDPE. Reprocessed material is recycled HDPE.

Polypropylene (PP) – ACM's second most used plastic; its advantages include strength, rigidity, fatigue resistance, heat resistance, and recyclability.

Special Materials

High Molecular Weight Polyethylene (HMWPE) - advantages: high tensile and compressive strength.

Low Density Polyethylene (LDPE) – advantages: flexible, high resilience, soft, pliable, and recyclable.

Crystal Polystyrene (PS) - Clear, rigid, and lightweight.

Thermoplastic Elastomer (TPE) – also known as thermoplastic rubber, a rubber based substance that is flexible and lightweight. TPE has advantages of both plastic and rubber.

Additives – when required ACM has used additives to make property improvements to products such as UV stabilizers.

Many Other Engineered Resins – ACM is not limited to processing the materials listed above and can process additional materials upon request. ACM can help define the material that meets customer needs and expectations.

ACM uses special materials only as specified by our customers. ACM does not use any additives or fillers without customer approval.

Polyurethane Foaming

ACM has an in house foaming system that can fill blow molded and thermoformed parts. Polyurethane foam is commonly used for its insulation properties and its ability to make plastic products more rigid.

Secondary Operations

Secondary operations involve work done to parts after the molding operation, typically by hand or with a fixture. Some secondary operations include trimming, drilling, cutting, flaming, and final finishing. ACM works with local machine tool companies to aid in the design and maintenance of Customers’ fixtures. Fixtures are typically used to aid with secondary operations that require higher quality, repeatability, and the use of mechanical tools such as drills, saws, mills, and hydraulics. They also provide additional safety to operators through guarding and eliminating the need for operators to manually perform the operations.


ACM offers assembly as a value added service. ACM will assemble products as requested by customers. Some assembly operations currently being done include: fastening, riveting, gluing, labeling, etc.


Currently ACM's painting capabilities involve a hand decorating line for a specific outdoor product. In the event that a Customer requests special painting or coating beyond hand painting, ACM will work closely with local coating companies to fulfill the requirement.


Many of ACM's customers’ products are packaged at ACM. ACM offers complete pack-off as a value added service. ACM works closely with local suppliers to meet customers' corrugated and packaging requirements.
