Gap pot­ting
The joints or edges between two vis­i­ble parts are par­tic­u­larly sus­cep­ti­ble to the ingress of dirt, dust and exter­nal media. By pot­ting these joint edges flush with the sur­face, the ingress of for­eign bod­ies and sub­stances can be effec­tively pre­vented. This not only ensures a clean and durable con­nec­tion, but also enables a higher IP pro­tec­tion class to be achieved, which sig­nif­i­cantly increases resis­tance to envi­ron­men­tal influ­ences.
Anti-​splinter film
The anti-​splinter film pro­vides effec­tive pro­tec­tion for glass front pan­els by pre­vent­ing the glass from break­ing and retain­ing dan­ger­ous splin­ters. This film not only increases safety, but can also sig­nif­i­cantly improve the shat­ter resis­tance of glass sur­faces. In addi­tion, it helps to reduce UV rays, which pro­tects the inte­rior from dis­col­oration.
Glass
Glass fronts on HMIs offer a mod­ern and user-​friendly sur­face that is both aes­thet­i­cally pleas­ing and func­tional. They pro­vide a clear view of dis­plays while pro­tect­ing them from dust and dirt. They are also easy to clean and con­tribute to the longevity of the device.

Front or dec­o­ra­tive foils
Front or dec­o­ra­tive foils for HMIs offer a flex­i­ble and cost-​effective solu­tion for the user inter­face of devices. They are light­weight and can be pro­duced in dif­fer­ent designs and col­ors to enhance the user expe­ri­ence. In addi­tion, films are resis­tant to envi­ron­men­tal influ­ences, which increases their longevity and func­tion­al­ity.
LOCA Opti­cal Bond­ing
LOCA Bond­ing (Liq­uid Opti­cally Clear Adhe­sive) is an advanced tech­nol­ogy that enables a vir­tu­ally bubble-​free bond between dis­plays and pro­tec­tive glass. By using liq­uid adhe­sive, excel­lent light trans­mis­sion is achieved, which sig­nif­i­cantly improves image qual­ity. This method also pro­vides addi­tional pro­tec­tion against shocks and vibra­tions, increas­ing the longevity of the devices.
OCA Bond­ing
OCA Bond­ing (Opti­cally Clear Adhe­sive Bond­ing) is a tech­nique that enables touch sen­sors and glass or film sur­faces to be seam­lessly bonded together, result­ing in opti­mum vis­i­bil­ity. This method reduces glare and improves colour inten­sity by min­i­miz­ing the dis­tance between the sen­sor and the cover. OCA bond­ing also pro­vides effec­tive pro­tec­tion against bumps and scratches, which increases the dura­bil­ity of the devices.
Touch sen­sor
Touch sen­sors are inno­v­a­tive input devices that enable intu­itive and user-​friendly inter­ac­tion with dig­i­tal dis­plays. They respond to touch and ges­tures, which con­sid­er­ably sim­pli­fies and speeds up the oper­a­tion of devices. With var­i­ous tech­nolo­gies such as capac­i­tive and resis­tive sen­sors, they offer ver­sa­tile appli­ca­tion pos­si­bil­i­ties in numer­ous indus­tries.

This method also pro­vides addi­tional pro­tec­tion against shocks and vibra­tions, increas­ing the longevity of the devices.
Air Gap Bond­ing
Air Gap Bond­ing is a bond­ing tech­nique that cre­ates an air­tight con­nec­tion between a dis­play and a pro­tec­tive layer with­out the use of opti­cal tape. This method reduces reflec­tions and improves vis­i­bil­ity by min­i­miz­ing the gap between the two sur­faces. It also allows for greater flex­i­bil­ity in the design, result­ing in slim­mer and lighter devices.
Dis­play
Dis­plays are essen­tial com­po­nents of mod­ern devices that present infor­ma­tion visu­ally and enable user-​friendly inter­ac­tion. They are used in a vari­ety of tech­nolo­gies, such as LCD, OLED and LED, and offer dif­fer­ent advan­tages in terms of image qual­ity and energy effi­ciency. In addi­tion, dis­plays are avail­able in var­i­ous sizes and for­mats to meet the dif­fer­ent require­ments of appli­ca­tions.
Mechan­i­cal but­tons
Mechan­i­cal but­tons are tried-​and-​tested oper­at­ing ele­ments that offer a pre­cise and reli­able user expe­ri­ence thanks to their tac­tile feed­back. They are widely used in a vari­ety of appli­ca­tions, e.g. in indus­trial con­trol sys­tems, and impress with their dura­bil­ity and robust­ness. Thanks to their indi­vid­ual design options, mechan­i­cal but­tons can be opti­mally adapted to the spe­cific require­ments of the respec­tive device.
Illu­mi­na­tion Logo
The illu­mi­na­tion of but­tons and logos not only improves vis­i­bil­ity in dark envi­ron­ments, but also gives devices an appeal­ing aes­thetic. By using LED tech­nol­ogy, col­ors and bright­ness can be cus­tomized to cre­ate dif­fer­ent user expe­ri­ences. Illu­mi­nated but­tons and logos also pro­mote user-​friendliness by mak­ing inter­ac­tion more intu­itive.
Capac­i­tive but­tons
Capac­i­tive but­tons use the change in the elec­tri­cal field to rec­og­nize touch, which enables respon­sive and user-​friendly inter­ac­tion. They offer a mod­ern, ele­gant design as they are often flush-​mounted and have no mov­ing parts. This tech­nol­ogy is par­tic­u­larly durable and resis­tant to wear and tear, which extends the life of the but­tons.
Mem­brane pro­cess­ing
Mem­brane pro­cess­ing for mem­brane key­boards includes var­i­ous processes to opti­mize the func­tion­al­ity and aes­thet­ics of the key sur­faces. These include the cut­ting, print­ing and lam­i­nat­ing of foils, which enable pre­cise adap­ta­tion to the respec­tive require­ments. These pro­cess­ing tech­niques not only ensure improved hap­tics, but also a longer ser­vice life and dura­bil­ity of the keys.
Mem­brane key­pads
Mem­brane key­pads are a ver­sa­tile and cost-​effective solu­tion for oper­at­ing devices that are char­ac­ter­ized by their flat design. They are made of flex­i­ble mem­brane mate­ri­als that inte­grate both the keys and the under­ly­ing cir­cuitry, which sim­pli­fies pro­duc­tion. These key­boards offer high resis­tance to envi­ron­men­tal influ­ences, such as mois­ture and dust, and are there­fore ideal for var­i­ous appli­ca­tions.
Sin­gle board com­puter
Sin­gle board com­put­ers are cen­tral com­po­nents in many elec­tronic devices and serve as a plat­form for pro­cess­ing and con­trol­ling infor­ma­tion. They inte­grate impor­tant func­tions such as proces­sors, mem­ory and inter­faces to ensure effi­cient data pro­cess­ing. With their com­pact design, com­puter boards are ideal for appli­ca­tions in var­i­ous indus­tries, from automa­tion tech­nol­ogy to portable devices.
Assem­bly
The assem­bly of printed cir­cuit boards is an essen­tial process in elec­tron­ics pro­duc­tion in which elec­tronic com­po­nents are pre­cisely placed on a printed cir­cuit board (PCB). Tech­niques such as auto­mated SMD assem­bly enable fast and effi­cient place­ment, ensur­ing high accu­racy and qual­ity. These processes are cru­cial for the func­tion­al­ity and reli­a­bil­ity of elec­tronic devices in var­i­ous appli­ca­tions.
Cables
Cables are indis­pens­able com­po­nents in elec­tron­ics that ensure a reli­able con­nec­tion between dif­fer­ent devices and sys­tems. They are avail­able in var­i­ous designs and mate­ri­als to meet dif­fer­ent require­ments in terms of cur­rent strength, data trans­mis­sion and envi­ron­men­tal con­di­tions. High-​quality cables make a deci­sive con­tri­bu­tion to sig­nal qual­ity and the longevity of the entire instal­la­tion.
Enclo­sures
Enclo­sures are cru­cial com­po­nents in elec­tron­ics that not only ensure the pro­tec­tion of inter­nal com­po­nents from exter­nal influ­ences, but also influ­ence the visual design of devices. They are avail­able in var­i­ous mate­ri­als, such as metal or plas­tic, and can be indi­vid­u­ally designed to meet the spe­cific require­ments of a prod­uct. Enclo­sures also con­tribute to heat dis­si­pa­tion and elec­tro­mag­netic shield­ing, which increases the per­for­mance and reli­a­bil­ity of the devices.
Car­rier plates
Car­rier plates are impor­tant ele­ments in elec­tron­ics that serve as a sta­ble basis for the assem­bly of parts and com­po­nents. They not only pro­vide struc­tural sup­port, but also help with heat dis­si­pa­tion and elec­tro­mag­netic shield­ing. With dif­fer­ent mate­ri­als and sur­face treat­ments, car­rier plates can be adapted to spe­cific require­ments and envi­ron­ments.
