Overview

Rail Interiors

Overview

Brentwood is a premier supplier of custom interior components to the international rail vehicle industry. We thermoform and injection mold functional and aesthetic parts that reduce weight by up to 25%, while also allowing railcar companies to comply with toxicity and environmental regulations. These interior trim and seating components can be formed using a range of materials and are easily integrated into the final build.

We specialize in forming rail-specific, low-smoke, low-toxicity (LST) materials and have completed technically demanding projects utilizing anti-graffiti, decorated PVC, and PVDF films. Brentwood also maintains strong research and development relationships with major resin manufacturers to test new and experimental materials, allowing us to provide customers with the most cutting-edge solutions.

Materials

Materials

Choosing the appropriate plastic material for your application is an essential step in developing a successful finished part. Each material has its own characteristics, properties, strengths, and weaknesses. Therefore, there are many factors that can influence material selection, ranging from performance to appearance to cost. By working with you to understand the parameters of your project, we’re able to help you choose the best, most-cost effective method to achieve your goals and meet regulations.

TPO

Thermoplastic Polyolefin is a compounded alloy containing rubber, a blend of polypropylene, and a reinforcing filler. It is a great replacement for metal parts as it provides high impact and chemical resistance.

ABS

This material is manufactured by combining three different compounds: acrylonitrile, butadiene, and styrene. In addition to its high stiffness factor and creep resistance, ABS is one of the most versatile plastics available.

HDPE

High-density Polyethylene is stronger and stiffer than standard polyethylene with good impact and abrasion resistance.

HIPS

High Impact Polystyrene is a versatile and cost-effective material that is easy to form. Despite its name, HIPS actually provides low impact resistance when compared with other thermoformable materials (it simply has a higher impact rating than other materials in the polystyrene family).

PC

Polycarbonate is extremely durable over a wide temperature range. It also offers high clarity, making it an ideal choice for transparent parts.

PVC

Polyvinyl chloride is stiffer than ABS and features high impact strength and natural flame-retardant qualities.

Films

Films

Depending on your material selection and project requirements, it may be necessary to cap the chosen material with a film. Films can be protective – to ensure that the material will be durable and long-lasting – or decorative – to enhance railcar interior aesthetics.

PVDF

Polyvinylidene fluoride is a protective film that can withstand exposure to harsh thermal, chemical, and ultraviolet conditions.

Acrylic

This film is designed to protect materials lacking high impact strength and durability while also providing a shiny, decorative finish.

Tedlar®

The Tedlar film is a specialty material designed to combat graffiti, keeping rail interiors clean for the lifetime of the part.

Project Management

Brentwood’s internal project management team is well-practiced at working with complex timelines and deadlines for rail projects. We ensure the manufacturing process flows smoothly from the first tooling order through final delivery. After that, project management works directly with our customer service team to make sure you can easily reorder parts.

Part Design

Part design is admittedly Brentwood’s favorite step in the development process. Our engineers collaborate directly with railcar interior planners to create new design possibilities that yield properly formed and aesthetically pleasing parts. The part design process also aids project planning and can reduce scrap rates to save time and money.

Assembly Design

Thermoplastic parts often require additional hardware in order to interface with the other components of the project. Brentwood’s assembly team joins these parts with the adhesive and mounting equipment necessary to produce fully completed assemblies. This ensures all parts can be easily incorporated into the final build.

Transport Packaging Design

Post-manufacturing, it is essential that all of your parts are delivered efficiently and undamaged. For that reason, we develop custom packaging designs that protect your parts while they are in transit.

Certifications

Certifications

IRIS

The International Railway Industry Standard (IRIS) is based on the ISO 9001:2008 quality certification and further incorporates rail-specific requirements to ensure all sourced parts are high quality and reliable.

IRIS
ISO9001 Certification

ISO 14001:2004

To create and maintain sustainable business practices, Brentwood has developed an environmental management system that minimizes the effects of our operations on the environment. This includes the design, manufacture, and assembly of plastic thermoforming products; the extrusion, calendering, and punching of semi-flexible thin-film PVC sheets; and the injection molding of plastic products.

ISO 14001:2004
ISO9001 Certification

ISO 9001:2008

This certification furthers Brentwood’s dedication to quality, enabling us to produce consistent, top-tier parts that meet your expectations. It includes the design, manufacture, and assembly of plastic thermoforming products and the extrusion, calendering, and punching of semi-flexible thin-film PVC sheets.
