E-bike drives: Well Protected and Perfectly Marked

Brose as the world’s fourth-largest automotive supplier in family ownership has transferred this know-how to e-bikes and designed an innovative drive system for electric bicycles. Brose applies the high quality standards of the automotive industry to e-bike drives as well.

Effective Protection against the Elements
The demands made on marking as well as tamper protection and anti-counterfeiting solutions for these electric motors are high as well. “In addition to retaining their visual appeal during their entire life, the labels must be UV- and weather-resistant, and withstand mechanical impacts such as gravel on the road,” says Brose. Specifically for these demands, the experts from Schreiner ProTech developed three different solutions: A label with a protective overlaminate effectively displays the manufacturer’s logo and optimally protects it against external influences. The second label is a nameplate which, in addition to marking the product, enables it to be authenticated by means of a complex, tamper-evident checkerboard film that is difficult to counterfeit. Furthermore, a housing closure seal with security slits on the e-bike motor reliably indicates potential tampering attempts.

Nameplate with venting function

SICK produces sensors that have to resist numerous environmental influences such as major temperature fluctuations and the effects of moisture in target applications. To vent such housings while maintaining ingress protection according to their IP code and to mark them, Schreiner ProTech has developed a nameplate that is provided with a pressure compensation seal (PCS).

Marking and Venting Combined Nameplate with venting function

Temperature fluctuations may result in excess pressure or vacuum in electronic housings. Pressure differences stress the assembly components and their individual elements and may cause damage resulting in the destruction of the electronic system. A pressure compensation seal regulates this pressure by means of its membrane and at the same time provides protection against external influences such as water or dust. For the sensor housing of a driverless transport system (FTF), SICK was seeking a solution for venting and marking, and opted for a pressure compensation seal from Schreiner ProTech. The solution saves a lot of space because marking and venting elements do not have to be installed side by side. The processing of the pressure compensation seal and nameplate in a single pass saves process times.

Documentation of Repairs: Serialized Marking Solution

Schreiner ProTech has developed a plastic clip with laser-engraved code and human-readable text, as well as two silver-colored labels made of Color Laser Film (CLF) for the Bosch QualityScan. As the world’s leading manufacturer of diesel injection systems, Bosch attaches major importance to top-quality repairs. Therefore, in the Bosch QualityScan, the company is now offering garages and consumers transparent web-based documentation of common rail component repairs by authorized garages. Schreiner ProTech supplies the elements for respective proof.

Two Solutions from a Single Source
“As a result, we’re receiving exactly the two solutions we need from a single source,” says Dirk Schoenfeld, Engineering Project Manager Automotive Aftermarket at Bosch, commenting on the innovative proof of quality. Account Manager Axel Müller from Schreiner ProTech explains: “By using our proven Color Laser Film and the new development for laser engraving the plastic clips, we were able to successfully achieve a solution for two different requirements.”

Avalanche Transceiver: Pressure Compensation Seal Protects Electronics

Devices used to search for avalanche victims increase the victims’ chances of survival many times over. The “Barryvox” high-tech tool by Mammut makes it possible to precisely locate several people due to highly complex electronics that have to resist harshest ambient conditions. Adequate electronics protection is provided by a rugged housing for which Schreiner ProTech supplies the pressure compensation seals (PCS). They ensure venting of the transceivers and prevent moisture ingress.

Functional Component for Protection against Excess Pressure and Moisture
Pressure compensation seals prevent excess pressure in the electronic housing and, at the same time, are completely impermeable to water due to a special membrane. “The membrane resisted our load test, which simulated a dive in an alpine brook”, says Ilari Dammert, Product Manager at Mammut. As a result, users can be assured that the transceivers also work in heavy snowfall, rain and wet conditions.

Tachograph: High-security Seal Protects against Tampering

Schreiner ProTech, together with Continental, has developed high-security seals that indicate attempts to tamper with tachographs by opening their housings at first glance. The seals combine a Void Effect, Hologram and sequential numbering

Visible Tampering Protection Thanks to Seals
When police officers or customs officials conducting routine checks suspected that drivers had not taken their mandatory breaks or spent more than the legally permissible time behind the wheel in the past, they had to perform complex examinations of the tachographs for potential tampering attempts. Tachograph housings consist of two parts that are closed with a screw. This is the weak area that allows people with criminal intentions to tamper with the device. The seals are placed precisely on top of the screw and the connecting edges of the housing parts. They immediately indicate if someone has tampered with the tachograph.

RFID Special Development: RFID Label (UHF) with a 4K Chip(UHF)

Schreiner ProTech, together with Siemens, has developed a new RFID label (UHF) with a 4K chip (4KByte) for Siemens’ new Simatic RF600 reader generation. The 4K chip offers 53 times more storage capacity than conventional RFID solutions. This capacity is required for complex processes in manufacturing control. In addition, manufacturing-relevant data is stored on the product or transport container in the automotive sector and in the process industry.

RFID Including Process Know-how
The technology corporation had three reasons for selecting Schreiner ProTech as its development partner: industry-specific process knowledge, specific know-how in manufacturing RFID labels, and knowledge of potential suppliers and cooperation partners.

Packaging of Plastic Vials: Breathable Container Closure

Re-sealable, dirt-repellant, air-permeable: Intelligent protective films often have to perform several functions. For a renowned biotech company, Schreiner ProTech has designed a special product solution which is breathable and thus prevents the packaging of plastic vials from bursting while being shipped as air freight. At the same time, the innovative cover protects the sensitive vials again dust and dirt.

Fully Automatic Processing that Includes Venting
The customer applies the Protective Film on a dedicated packaging line in a clean room environment. Fully automated processing of the material ensures reliable sealing of the blister packs. Thanks to the venting function of the Protective Film, the blister packs sustain no damage during air shipment and hygienic handling of the vials is assured.
