For projects requiring a new production tool, our mold and tool manufacturing services can support the transition from product design through production tooling and molding.
Plastic blow molding provides an efficient manufacturing method for hollow cosmetic and personal care packaging.
Hi-Rel Plastics & Molding offers extrusion blow molding (EBM), injection blow molding (IBM), and injection stretch blow molding (ISBM) capabilities for custom hollow plastic products and packaging.
Applications can include:
Depending on product requirements, materials can include HDPE, LDPE, PP, PET, RPET, polycarbonate, specialty copolyesters, and other thermoplastic materials.
Hi-Rel Plastics & Molding also supports custom blow mold manufacturing, helping customers develop proprietary packaging shapes and custom products rather than being limited to standard stock packaging.
Liquid silicone rubber offers flexibility, durability, soft-touch characteristics, temperature resistance, and excellent performance for many beauty and personal care applications.
Hi-Rel Plastics & Molding provides LSR (liquid silicone rubber) injection molding for products such as soft-touch cosmetic applicators, skincare applicators, flexible seals, dispensing valves, membranes, beauty device components, brush grips, grooming components, flexible inserts, wearable beauty-product components, and other custom silicone parts.
LSR molding can also be combined with rigid components when a product requires both structural strength and a flexible or soft-touch interface.
Thermoforming and vacuum forming provide economical solutions for cosmetic and personal care packaging, product protection, display components, and larger formed parts.
Applications include:
Thermoformed trays can help protect delicate cosmetic products while improving organization, presentation, and handling throughout manufacturing, shipping, and retail distribution.
For larger plastic products used by cosmetic and personal care manufacturers, rotational molding can provide durable hollow components with excellent impact resistance.
Applications may include bulk ingredient handling bins, large storage containers, mixing containers, transport carts, waste collection containers, material handling bins, durable storage products, and other heavy-duty components used throughout cosmetics and personal care manufacturing facilities.
A successful custom cosmetic component begins with properly engineered tooling.
Hi-Rel Plastics & Molding provides mold and tool manufacturing for injection molding, blow molding, LSR molding, thermoforming, vacuum forming, and rotational molding programs.
Tooling support can include product evaluation, Design for Manufacturability (DFM), mold design, prototype and production tooling, mold flow considerations, mold sampling, validation, engineering modifications, tool transfer, mold repair, refurbishment, and preventive maintenance.
This integrated approach allows customers to move from product concept and CAD data through tooling and production with one manufacturing partner.
Early design decisions can significantly affect cosmetic appearance, product functionality, tooling cost, manufacturing efficiency, and long-term production quality.
Hi-Rel Plastics & Molding provides engineering and 3D printing / rapid prototyping support to help customers evaluate designs before committing to production tooling.
Prototype components can be used to evaluate overall dimensions, fit, assembly, ergonomics, appearance, functionality, packaging concepts, and design changes. Our engineering team can also provide DFM guidance intended to improve moldability, manufacturability, consistency, and production efficiency.
A molded component often requires additional operations before it is ready for final product assembly or the consumer market.
Hi-Rel Plastics & Molding provides a broad range of secondary manufacturing services that can reduce the need to coordinate multiple outside vendors.
Available services include:
These services can be particularly valuable for cosmetic and personal care products where appearance, branding, assembly quality, and consumer presentation are important parts of the finished product.
Brand presentation is especially important in cosmetics, skincare, and personal care products.
Hi-Rel Plastics & Molding offers pad printing and other secondary decoration services for logos, identification marks, graphics, instructions, branding, and other decorative requirements on molded components.
Depending on the product and substrate, additional options can include hot stamping, heat transfer, labeling, painting, coating, and other surface treatments.
Combining molding and secondary decoration can simplify the cosmetic packaging supply chain and help maintain consistency from molded component through finished product.
Hi-Rel Plastics & Molding can support projects beyond individual molded components through assembly and contract manufacturing services.
Capabilities include mechanical assembly, clean room assembly, cable assembly, component integration, ultrasonic welding, adhesive bonding, heat staking, inspection, packaging, and other value-added operations.
Customers can therefore source tooling, molding, secondary operations, assembly, and packaging through one manufacturing partner, reducing supplier complexity and helping streamline production.
For selected cosmetics, skincare, personal care, dispensing, or other applications requiring greater environmental control, Hi-Rel Plastics & Molding offers Class 10,000 / ISO Class 7 cleanroom and Class 100,000 / ISO Class 8 cleanroom environments.
