Integrated injection molding manufacturing, 3PL fulfillment, and distribution.
U.S.-based injection molding directly into customer inventory, e-commerce fulfillment, retail distribution, or contract-manufacturing releases—without requiring a separate fulfillment partner. Mars Plastics offers 24-hour U.S. production, dedicated inside customer representatives, quality assurance, and support from design through delivery.
Mars Plastics provides integrated 3PL fulfillment and distribution services; contract manufacturing fulfillment, warehousing, direct-to-consumer order fulfillment, kitting, packaging, and nationwide distribution from one U.S.-based partner for plastic products, components, and finished assemblies. By combining plastic injection molding, contract manufacturing, inventory management, packaging, and shipping, we help customers move products efficiently from production to distribution centers, retail locations, business customers, and individual consumers.
Instead of manufacturing products at one facility and transferring them to a separate warehouse or fulfillment provider, customers can rely on Mars Plastics for a streamlined production-to-delivery process. Our team supports product programs from design through delivery, with U.S.-based production, quality assurance, responsive customer support, and efficient fulfillment solutions.

Direct-to-Consumer Fulfillment
For brands selling online, Mars Plastics can support direct-to-consumer—or DTC—fulfillment for plastic products and assemblies. We receive customer orders, pick items from managed inventory, prepare them for shipment, and coordinate delivery directly to the end customer.
This service is a strong fit for e-commerce brands, product inventors, subscription programs, replacement-part programs, and companies that want to sell nationwide without managing a separate warehouse operation.
Direct-to-consumer fulfillment services may include:
- Storage of finished inventory after molding or assembly
- Individual-order picking and packing

By keeping production and fulfillment connected, Mars Plastics helps brands reduce product handling and simplify the path from manufacturing to the customer’s doorstep.
Contract Manufacturing Fulfillment
Mars Plastics also supports larger-scale contract manufacturing fulfillment for customers that require recurring production, scheduled inventory releases, and multi-location distribution.
This model is designed for OEMs, wholesalers, retailers, distributors, industrial companies, and private-label brands that need a dependable source for molded plastic components or finished products—along with the logistics infrastructure to store and release that inventory as needed.
Our contract manufacturing fulfillment programs can support:
- Scheduled production runs and replenishment programs
- Finished-product warehousing
- Just-in-time inventory releases
- Shipments to customer facilities and assembly plants
- Distribution to multiple warehouses or regional locations
- Bulk, case-pack, palletized, and truckload shipments

- Packaging, labeling, and assembly requirements
- Release schedules aligned with customer demand
Whether products ship by the individual unit, case, pallet, or truckload, Mars Plastics helps customers maintain a more organized and responsive supply chain.
