The master thesis deals with design to produce terminal using the plastic injection molding. In the first part are theoretical information about injection molding and injection molding with inserts. The second part is a concrete design of production terminal which contains: injection mold design, calculation of the injection parameters, machine selection, technical and economic evaluation of production. Terminal is made of polyamide 66, inserts material is brass. Parts of injection mold assembly are selected from Hasco standards. The main parts of assembly are made of 1.2312 steel. Production cycle is placed on injection machine Allrounder 375 V from Arburg.

The master´s thesis is focused on technology of injection plastics. The specified part is guard cover of mobile phone. The first part of thesis is focused on description of technology with priority on construction of form. The second part of thesis includes calculations of parameters, which are needed for production, along with techno-economic evaluation of selected construction design.

Thermoplastic injection technology is widely used in all sectors of consumer electronics and automotive industry. The biggest advantage of this manufacturing technology is a high degree of automatization and good reproducibility of the manufacturing process. Another advantage is the possibility of recycling of the gating scrap and defective products. The main task of this work is to calculate the necessary parameters for the injection process, which takes place at the designed injection form. Next part is technical design which includes choice of standard parts of injection mold and idividual semi-finished parts for mold. Thesis continues with selecting the type of injection press based on calculated parameters of the injection process. Thesis is finished by technical-economic evaluation.
