Front-end carrier

The front-end carrier is a structural part that supports the radiator, headlamps, bonnet catch and stoppers, among other elements. Front-end design, along with bumper design, is the field in which Btechc has the most experience, thanks to our technicians who specialise in this part of the car. The specific design of the front-end depends on the manufacturer’s strategy for assembling the front-end carrier on the vehicle and its specifications.

Technology:

• Welded sheet metal: high-performance, heavy, high per unit price and significant investment in tooling.
• Full plastic: low performance, light, inexpensive and limited investment.
• Hybrid: mid to high performance, mid to low weight and mid-level investment. The plastic element can be overmoulded or attached mechanically.

Development:

• Selecting the right technology for the vehicle specifications, the number of units and investment
• Estimating the price per piece
• Creating the preliminary project based on the setting and the governing surfaces.
• Developing the parts in the three existing types of technology: sheet metal, full plastic and hybrid
• Analysing tolerance for front-end carrier mounting

Integrating functions. We specialise in cutting costs to integrate functions on full plastic or highbred frontends:

• Headlamp mounts
• Locks
• Cables
• Bonnet rods
• Airbag sensors
• Air channels
• Bumper mounts
• Bowden cable
• Air deflector

Movable parts

The technical evolution of vehicles has led movable parts – doors, bonnets and lids – to include more elements and increasingly sophisticated technology. In the initial design stage, it is important to conduct cinematic studies, as these will be the basis for designing both the part itself and the body of the vehicle.

Doors

• Cinematic study
• Door structure design
• Hinge design
• Door module/panel design
• Watertight systems
• Stiffness calculations and frequencies
• Integrating mechanisms
• Window mounting solutions

Lids

• Cinematic study
• Selection of gas shocks
• Hinge design
• Structural bonnet design
• Stiffness calculations and frequencies
• Integrating catadioptric systems, indicator lights, brake lights, windscreen wipers and spoiler
• Windscreen mounting solutions

Body

The body design for a vehicle involves several variables such as structural stiffness, safety in the case of impact, acoustics, etc. high-strength steel is used to absorb the energy produced by an impact, meaning the steel can be thinner and the body, lighter. As the Young module for this type of steel is very similar to that of conventional steel, this can lead to a lack of stiffness in the body. This is why we include CAE simulation in the body design process.

Support for body design:

• Floorboards
• Dashboard
• Beams
• Side panels
• Roof
• Boot

Design taking into account:

• Soundproofing
• KTL anticorrosion treatment
• Paint
• Laser/point/TIG welding
• Dynamic and static stiffness simulations

Exteriors

In designing the plastic pieces for the exterior of the vehicle, it is essential that they have a perfect finish, as required for class A surfaces (with no visible or aesthetic defects). In order to do so properly, we have a multidisciplinary team of experts in materials, plastic part design, paint, moulds and injection.

Bumpers: comprehensive development of front and rear bumpers from standard and surrounding surfaces and list of requirements. Components:

• Coating
• Reinforcement
• Grilles and emblems
• Fixed and movable guides
• Spoilers and diffusers
• Pedestrian protection

Developing parts for the outside of the vehicle including:

• Handles
• Wheel well
• Fuel doors
• Sacrifice panels
• Threshold plates
• Running boards
• Deflectors

Interiors

Ergonomics, functionality, finishings and safety are some of the characteristics that must be taken into account when designing the inside of a vehicle.

The development department has extensive experience both with visible elements –such as door panels, centre consoles, dashboards, etc.– as well as parts that are not visible –like the Interior crossbeam, internal supports and air conducts, among others.

Dashboard and console. The dashboard is one of the most complex inner trim systems, given the large number of pieces that come together here, the mechanical specifications it must meet and the passive safety requirements. Here at Btechc we have technicians that specialise in the following groups of components:

• Dashboard (hood, lining and structure)
• Consoles
• Facings and button components
• Diffusors
• Glove box component
• Driveshaft area

Interior crossbeam. By applying our patented hybrid technology, Btechc can help reduce investment and make the interior crossbeam lighter.

Using bolts helps improve the joints between the plastic and the metal and makes it possible to use block frames in the injection process.

Interior finishings. Developing components for inside the vehicle including:

• Door panels
• Interior lining
• Interior posts
• Ceiling linings
• Hatchback lid
• Boot linings
• Interior lighting systems

Electrics

The electric and electronic parts of vehicles are becoming more and more important, which means we must have a team specialised in this discipline. Our professionals can create electric circuit diagrams and layouts with circuit boards, sensors and motors taking into account the location of these parts within the vehicle and the pertinent insulation in each case.

Services:

• Creating technical specifications
• Developing electronics for equipment
• 2-D/3-D layout in the vehicle
• Electric simulation
• Simulation of thermal dissipation of circuits
