Our goal is to help customers move from product idea to finished product with one experienced manufacturing partner.

Bankier serves a wide range of industries, including consumer products, medical, electronics, industrial, automotive, food packaging, and cosmetic packaging. We also support other markets that need dependable plastic components, assembly, packaging, or distribution services. 

Plastic injection molding is a manufacturing process used to make plastic parts in large quantities. Heated plastic resin is injected into a mold, cooled, and then removed as a finished part.

This process is often used when a product needs strong, repeatable, and precise plastic components.

Bankier offers custom plastic injection molding for a wide range of part sizes and production needs. Our injection molding capabilities include precision molded parts, close-tolerance components, insert molding, overmolding, tooling support, and production services.

We work with customers who need more than basic molding. Our team can also support design, material selection, assembly, packaging, and supply chain management.

Yes. Bankier provides product design and development services for plastic parts and components. Our team can help with concept development, product engineering, CAD modeling, prototyping, design for manufacturability, and design for assembly.

This helps customers improve part performance, reduce costs, and avoid problems before full production begins.

Design for manufacturability, or DFM, means designing a product so it can be made efficiently, consistently, and cost-effectively. For plastic injection molding, this may include reviewing wall thickness, material flow, mold design, part strength, surface finish, and assembly needs. 

DFM can help reduce tooling issues, lower production costs, and improve the final product.

Yes. Material selection is an important part of every plastic manufacturing project. Bankier can help evaluate resin options based on strength, flexibility, chemical resistance, heat resistance, appearance, durability, and cost.

Choosing the right plastic material early can improve product performance and reduce manufacturing risk.

Many thermoplastic materials can be used in plastic injection molding. Common materials may include ABS, polypropylene, polyethylene, nylon, polycarbonate, and other engineering resins.

The best material depends on the product’s use, environment, performance needs, appearance, and budget.

Yes. Bankier offers precision tooling and mold support for plastic injection molding projects. Tooling is a key part of producing accurate and repeatable molded parts.

Our capabilities include mold design, precision mold building, mold-flow analysis, mold-heat and cooling simulation, mold texturing, laser engraving, and related tooling services.

Mold design affects part quality, production speed, appearance, and cost. A well-designed mold helps plastic flow properly, cool evenly, and produce consistent parts.

Poor mold design can lead to defects, delays, higher costs, and inconsistent product performance.

Yes. Bankier can review existing plastic parts to identify ways to improve quality, performance, manufacturability, or cost. This may include material changes, tooling updates, design improvements, or process changes.

This is often useful when a part is too costly, difficult to assemble, or not performing as expected.

Yes. Bankier offers rapid prototyping and product development support. Prototypes allow customers to test a design, review fit and function, and make improvements before investing in full production tooling.

Prototyping can reduce risk and help bring better products to market faster.

Insert molding is a plastic injection molding process that places another component, such as a metal piece or preformed part, into the mold before plastic is injected around it. 

This process can improve strength, reduce assembly steps, and create a more reliable finished component.

Overmolding is a process where one material is molded over another material or part. It is often used to add grip, improve comfort, protect components, or combine multiple functions into one part.

Overmolding is useful for handles, seals, buttons, covers, and other parts that need a strong base with a specific surface feel, grip, or protective finish. 

Yes. Bankier offers thermoforming services. Thermoforming uses heated plastic sheets that are formed over a mold to create a finished shape.

Thermoforming can be a cost-effective option for certain parts, especially low- to medium-volume production runs, large parts, prototypes, trays, covers, and packaging components.

Injection molding uses melted plastic resin injected into a mold. It is often best for high-volume parts, complex shapes, tight tolerances, and strong repeatability.

Thermoforming uses a heated plastic sheet formed over a mold. It is often best for larger parts, lower tooling costs, faster startup, and low- to medium-volume production.

Bankier can help determine which process is the better fit for your project.

Yes. Bankier provides plastic fabrication services, including CNC machining and sheet fabrication. These services are useful for plastic components that require cutting, drilling, forming, bending, gluing, edge polishing, or tight dimensional accuracy.

Plastic fabrication may be used on its own or as part of a larger manufacturing program.

Yes. Bankier offers decorating and finishing services for plastic parts. These services may include pad printing, silk screening, hot stamping, painting, vacuum metallization, electroplating, PVD coating, and other finishing methods.

Decoration is considered early in the design process so that the part, material, and finish work together correctly.

Yes. Bankier provides contract assembly services for products that need careful manual work, automated assembly, kitting, testing, or specialized fixtures. 

Our contract assembly services help customers reduce internal workload, improve consistency, and scale production when demand changes.

Yes. Bankier offers contract packaging, also called co-packing. Services may include clean room assembly, display assembly, gift set assembly, repacking, cartoning, gluing, shrink-banding, pouching, bagging, wrapping, sealing, labeling, lot coding, sorting, reworking, fulfillment, warehousing, and distribution.

This allows customers to manage production and packaging through one manufacturing partner.

Bankier supports projects that require strong quality systems and careful production controls. Bankier is ISO 9001:2015 certified and maintains FDA-related registrations. 

Customers with regulated products should contact Bankier directly to discuss project requirements, materials, packaging, documentation, and quality needs.

Bankier follows a quality-focused manufacturing approach supported by ISO 9001:2015 certification and Six Sigma protocols. Quality is built into the production process, not treated as a final step only.

This helps ensure parts and products are made to customer requirements, on time, on spec, and on budget.

Yes. Bankier helps customers reduce costs through value engineering, design for manufacturability, material selection, process planning, vertical integration, assembly planning, and supply chain management.

Cost savings often come from better product design, fewer assembly steps, smarter material choices, and less reliance on outside vendors. 

Vertical integration means one company manages several stages of the manufacturing process. For Bankier, this can include product development, tooling, injection molding, thermoforming, decorating, assembly, packaging, warehousing, and distribution.

This approach can reduce delays, improve communication, simplify project management, and give customers one clear point of contact.

Comprehensive Product Responsibility, or CPR, is Bankier’s end-to-end approach to manufacturing. It means Bankier can serve as a single point of contact from concept development through production, packaging, warehousing, and distribution.

CPR helps reduce vendor handoffs, lower risk, speed up production, and simplify communication.
