QUESTION: 4 What is the specificity of the equipment?

- Technology for surface mounting (SMT Module Placement Machine Panasonic)
- Automatic optical inspection (AOI Marantz Electronics U22XH)
- Automatic soldering equipment (ERSA N-Wave 330 – Wave Soldering Machine)
- PCB line (Reflow Oven)
- Laser marking and engraving (FOBA M2000 – Lazer Marking);
- Production of plastic details (Engel Victory 1350/300 Tech – Injection Moulding Machineрр Engel Victory 330/110 Tech – Injection Moulding Machine , Engel Victory 750/160 Tech – Injection Moulding Machine)
- Test and calibration equipment ( ZERA MTS140 – Meter test system and ZERA MTS320 – Meter test system)
- ERP system for storage and movement of resources
Our injection molding machines are high-tech systems with automatic loading, mixing and process control and have simulation software that visualizes processes and allows precise adjustment, which ensures high speed and accuracy. The computer interface transfers all process settings to the machines, and the process completes a protocol (Infolog), which records the production of each part. Each machine is equipped with a robot for the finished parts, which is a guarantee of quality of the products.
Highly qualified specialists develop the stages of production of each product, set all parameters, monitor the environment, consumables, tests and accessories and monitor critical for the product characteristics and factors that affect its quality.
QUESTION 5: Why is it worth contacting ADD Bulgaria if you need production services?

Production processes are controlled at 3 levels:
- at the input level – supplier, material, technology;
- through systems determined by the high level of the equipment, which regulate and maintain the parameters of the processes;
- control through the Quality Assurance Systems-ISO 9001; MID-D; Measurement and inspection laboratory;
Production and delivery times are flexibly planned according to customer requirements.
