Plastics Manufacturing Equipment

Plastics manufacturing facilities often encounter stubborn residues, mold buildup, and equipment contamination, leading to production inefficiencies and quality issues. Common equipment and cleaning challenges include:

Injection Molding Machines

Residue buildup, mold release agents, and polymer flash can accumulate on molds and affect production quality.

Blow Molds: Accumulation of polymer residues, mold release agents, and contaminants can impact the quality and consistency of blow-molded products.

Compression Molds: Residual polymers, mold release agents, and oxidation can adhere to compression molds, affecting mold integrity and product quality.

Urethane Molds: Sticky urethane residues and mold release agents can build up on urethane molds, leading to production defects and mold deterioration.

Textured Molds: Fine textures on molds can trap residues and contaminants, requiring specialized cleaning methods to ensure thorough removal without damaging the mold surface.

Medical Molds: Stringent cleanliness standards in medical manufacturing require precise cleaning of molds to prevent contamination and ensure product safety and compliance.

Technical Molds: Complex geometries and tight tolerances in technical molds demand thorough cleaning to maintain mold performance and product quality.

Extrusion Lines

Residual polymers, carbon deposits, and contamination on screws, dies, and barrels can hinder production efficiency and product quality.

Conveyor Systems

Dirt, grease, and polymer residues can accumulate on conveyor belts, rollers, and guides, causing operational disruptions and product contamination.

Molds and Tooling

Molded parts often require precise cleaning to remove residue, flash, and release agents without damaging delicate surfaces.

Cooling Towers

Scale, algae, and biofilm buildup can reduce cooling efficiency and pose sanitation risks.


Residual polymers, oils, and other contaminants can accumulate on oven surfaces, affecting heat distribution and product quality. Proper cleaning of oven interiors is essential to ensure consistent heating and prevent contamination of baked or cured products.

What types of equipment and surfaces in the plastic manufacturing industry can be cleaned using dry ice blasting?

Dry ice blasting can be used to clean a wide range of equipment and surfaces in the plastic manufacturing industry, including molds, extrusion dies, injection molding machines, conveyor belts, cooling towers, and more. It is suitable for cleaning various types of plastics, including thermoplastics and thermosetting plastics, as well as other materials commonly used in plastic manufacturing.

How does dry ice cleaning compare to traditional cleaning methods in the plastic manufacturing industry?

Dry ice cleaning offers several advantages over traditional cleaning methods such as manual scrubbing, solvent cleaning, and abrasive blasting. Unlike these methods, dry ice blasting is non-destructive, non-abrasive, and environmentally friendly. It does not involve the use of water, chemicals, or abrasive media, making it ideal for use in plastic manufacturing environments. Dry ice blasting is also faster and more efficient, reducing downtime and labor costs associated with manual cleaning. View Comparison Chart

Can dry ice blasting remove stubborn contaminants such as mold release agents and polymer residues from plastic manufacturing equipment?

Yes, dry ice blasting is highly effective at removing stubborn contaminants such as mold release agents, polymer residues, grease, oil, and other residues from plastic manufacturing equipment and surfaces. The kinetic energy of the dry ice pellets helps to dislodge contaminants from surfaces, while the rapid sublimation process lifts away residues without leaving behind any residue. Dry ice blasting can clean even the most intricate plastic molds and components with ease.

Is dry ice blasting safe for use on plastic manufacturing equipment and delicate plastic surfaces?

Yes, dry ice blasting is safe for use on plastic manufacturing equipment and delicate plastic surfaces when performed by trained professionals. The process does not involve the use of water, chemicals, or abrasive media, so there is no risk of damage to the plastic surfaces. Dry ice blasting is non-conductive and non-abrasive, making it safe for use on sensitive electronic components and delicate plastic parts.
