What Injection Molding and Contract Manufacturing Services Does EVCO Plastics Offer?

EVCO Plastics is a global plastics manufacturing company whose core service is plastic injection molding, supported by contract manufacturing, mold design and build, and product design and development work. It is a fit if you need a manufacturing partner that can stay involved from early design through production rather than only quoting a part to print. The company operates multiple facilities, including locations in Dongguan, China; Juarez and Monterrey, Mexico; and Oshkosh, DeForest, and Calhoun in the United States, which matters if your project needs regional production or supply-chain flexibility.

Injection molding capabilities

Injection molding is the center of what EVCO does. The site groups its capabilities around several areas that indicate the kind of work it takes on:

• Plastic injection molding — the primary service, covering molded plastic parts.
• Medical & healthcare — molding work for medical and healthcare applications.
• Large parts — capability for larger molded components, which typically require different tonnage and tooling considerations than small precision parts.
• State-of-the-art technology — the company positions its equipment and technology as a differentiator.

The practical takeaway: if your project involves molded plastic parts, especially in medical/healthcare or large-part categories, this is within the stated scope. If your part is small, highly cosmetic, or in a specialty material not mentioned, you would need to confirm fit directly, since the site does not list every material or process.

Contract manufacturing

EVCO describes contract manufacturing as: "The parts you need – engineered, designed and built the way you need them." That framing points to a build-to-requirement model rather than a fixed catalog. In practice, contract manufacturing at this kind of supplier usually means the manufacturer takes responsibility for engineering, design, and production of the parts according to the customer's specification, instead of the customer buying a standard product.

This is relevant if you have a defined part or assembly need but want the manufacturing partner to handle engineering and production decisions rather than managing each step yourself.

Mold design and build

Mold design and build services are listed as a distinct offering. This matters because tooling is often the longest-lead and highest-cost part of an injection molding project. Having mold design and build in-house (or coordinated by the same partner) can reduce the handoff risk between a separate tool shop and the molder — a common source of delays and fit issues.

If your project requires new tooling, ask specifically whether mold design, build, and sampling are handled under one contract and how tool ownership and transfer work.

Design and development collaboration

The site's central message is collaborative: "At EVCO, we work alongside you until your project is fully formed," and "Through the whole process, we're here to collaborate and create with you." The listed journey runs from product design and development through production, under the heading "Your Journey, Our Expertise."

So the working model is end-to-end involvement: design and development support, then mold design and build, then injection molding and contract manufacturing. That suits teams that want one partner across the lifecycle rather than sourcing design, tooling, and molding separately.

Company credentials worth knowing

• Certified Women's Business Enterprise (WBE) — certified by the Women's Business Enterprise National Council (WBENC), affirming at least 51% women ownership, control, operation, and management. This can matter for supplier-diversity requirements in some procurement programs.
• Sustainability rating — EVCO advanced past the EcoVadis Fast Mover designation and earned a Bronze Rating, placing it in the top 35% of assessed companies. Relevant if your sourcing criteria include sustainability scoring.

How to decide if it fits

The site does not publish pricing, minimum order quantities, or lead times, so those need to be raised in a direct inquiry. If your project depends on a specific resin, tolerance, or volume band, ask about it explicitly rather than assuming coverage from the capability categories above.
