NBI delivers precision, made-to-print plastic components using Mold Injection, Molding Press operations, extrusion, thermoforming and CNC machining. Whether you need high-volume injection parts, molded press components or precision-machined polymer parts, we offer end-to-end manufacturing, finishing and assembly to meet your performance, cost and timing goals.
Plastic parts are engineered components made from thermoplastics and thermosets using a variety of manufacturing methods. They provide lightweight, corrosion-resistant, and highly configurable solutions. At NBI we specialize in Mold Injection (injection molding), Molding Press work (press-molding/transfer/ compression operations), extrusion, thermoforming, blow molding, and CNC machining — enabling designers to consolidate assemblies and optimize cost at volume.
Also called injection molding, Mold Injection is our primary high-volume production method. Plastic pellets are melted and forced into a closed mold (mold cavity) under high pressure. This process produces complex geometries, fine detail, thin walls and repeatable dimensions with fast cycle times. Typical applications: housings, snap-fits, cosmetic parts, valve bodies and assembly components.
When to choose Mold Injection: high volumes, complex parts, integrated clips or inserts, and tight cosmetic requirements.
We operate Molding Press equipment for thermoset components, compression molded parts, and specific press-molding applications where a press-based process provides advantages (for example, large-area panels, thick-section thermoset parts, or elastomeric components). Molding presses are used when the part geometry or material requires pressing rather than injection — e.g., certain gaskets, rubber-overmolded components, and high-temperature thermoset housings.
When to choose a Molding Press: thermoset materials, elastomers, thick sections, or compression/transfer molded geometries.
Continuous production of profiles, tubing and sheets via forced flow through dies. Best for long sections and constant cross-sections (channels, seals, frames).
Heated plastic sheets are formed over molds using vacuum or pressure. Economical for large panels, trays and medium-run parts.
Used for hollow components — bottles, reservoirs and tanks — by inflating a heated parison inside a mold.
Precision subtractive work (turning, milling, drilling) for prototypes, low-volume parts, and engineering plastics like POM, PTFE and Nylon. Ideal when tight tolerances or post-machining are required.
We select polymers to match mechanical, thermal, chemical and regulatory needs:
PET (Polyethylene Terephthalate): clarity and barrier properties — packaging, food-contact containers.
PP (Polypropylene) & ABS: injection molding workhorses — enclosures, trims, consumer goods.
PC (Polycarbonate) & Nylon (PA): high impact resistance and thermal stability — connectors, tool housings, lighting.
POM (Acetal), PTFE (Teflon), HDPE: low friction, chemical resistance — bushings, seals, insulators.
Thermosets & Elastomers: materials for Molding Press work and overmolding (rubber seals, gaskets).
High-performance & recycled polymers: LCP, PEEK, recycled resins available on request.
Material certificates and recommendations provided with samples and production runs.
We combine Mold Injection and Molding Press capacities with downstream processes so you get production-ready parts.
Injection presses covering small to large-tonnage machines for parts from grams to multi-kilo components.
Single- and multi-cavity tooling; insert molding and overmolding capability.
Hot-runner and cold-runner tooling options.
Molding press lines for compression and transfer molding of thermosets and elastomers.
Press sizes and platen capacities to support large panels, thick-section parts, and rubber-overmolding applications.
Precision tooling and controlled press cycles for consistent cure and surface quality.
Extrusion lines for profiles and sheet feedstock.
Thermoforming and vacuum forming stations.
CNC machining centers for plastic bar/rod/plate finishing (tight tolerances).
Secondary: ultrasonic welding, sonic welding, insert installation, pad printing, laser marking and full assembly lines.
Mold design, rapid prototype molds, sample runs and pilot production for Mold Injection and press tooling validation.
In-process inspection, color & gloss controls, dimensional reports (micrometers, gauges).
Capable of prototype → small batch → high-volume production with process controls to stabilize cycle-to-cycle quality.
Cosmetic finishes: Class-A surfaces, textures, gloss or matte finishes.
Marking & printing: pad printing, screen printing, laser marking.
Coatings & plating where applicable: protective coatings, low-VOC paints.
Assembly & inserts: metal insert molding, overmolding, ultrasonic welding, bonded assemblies.
Sustainability options: recycled-material parts and low-emission process options.
NBI’s plastic parts are used across many sectors:
Automotive: molded clips, interior trims, snap-fit housings, overmolded rod ends.
Electronics & Lighting: ABS/PC enclosures, bezels, connector insulators, heat-resistant parts.
Medical & Laboratory: instrument housings, fixtures, non-implantable components (with compliant materials).
Consumer Goods & Appliances: knobs, covers, dispensers and decorative panels.
Packaging & Fluid Systems: blow-molded containers, valve components, molded seals and washers.
Mold Injection & Molding Press expertise: we operate both injection molding and press-molding lines to match material & geometry needs.
One-stop production: tooling → molding/pressing → CNC finishing → surface treatments → assembly.
Material guidance: polymer selection and DFM to lower cost and improve part life.
Quality & traceability: batch control, material certificates and dimensional inspection.
Sustainability options: recycled resins, eco-friendly coatings and waste-reduction strategies.
15+ years experience delivering consistent production and supply reliability.
A: Mold Injection (injection molding) injects molten thermoplastic into a mold cavity — ideal for thermoplastics and high-volume parts. Molding Press refers to press-based molding operations (compression, transfer or thermoset pressing) used for thermosets, elastomers or thick-section parts that require pressing rather than injection.
A: Yes — both insert molding during Mold Injection and overmolding (including rubber overmolding using a Molding Press where appropriate) are standard services.
A: Yes — we can evaluate recycled resin options for suitable applications and will provide material performance data.
A: Tooling lead time depends on complexity and cavity count; Mold Injection tooling typically takes longer than prototype machining, while Molding Press tooling varies for thermosets. We provide estimated lead times with each quote.
