COVI Hardware Maker is equipped with the advance facilities such as high speed CNC machine centers, high mirror polishing EDM machines, high precision Wire-cut machines, inspection equipment from Sodick, FANUC, Mitsubishi, Korean and Taiwan, which guarantees the high quality and tight tolerance of molds.
We always use high quality steels such as 718, 738, S136 and 8407 from ASSAB of Sweden, GS-738 and GS-711 from Thyssen of Germany, NAK80 from DAIDO of Japan and P20, 420. And we always use mould bases and standard components such as LKM, DME, HASCO, FUTABA etc.
With rich experience of many kinds of mold construction and mechanism, COVI Hardware Maker is able to construct a wide variety of molds and components that will work efficiently, effectively and accurately, while at the same time keeping the customer's cost as low as possible. Minimum material waste, reduction or elimination of scrap, low maintenance, and long mold life are the standards in a well built mold.
We are familiar with hot runner systems such as MOULD MASTER, Master TIP, HUSKY, HASCO, DME, YUDO, INCOE, THERMOPLAY, Synventive etc. With hot runner system you can eliminate sprues and runners, decrease cycle time per part, improve consistency in the part, and allow for better control of the overall molding process.
We have the ability of making Automatic Unscrewing Molds which are used for molding parts which contain internal threads. Tight tolerances in the internal gearing are critical to ensure proper core extraction speed for accurate and reliable threading.

COVI Hardware Maker prides itself on its high-end, high quality, long life hard molds with high precision. We can produce molds that can produce plastic parts within a tolerance of +/- .0004 inch.
COVI Hardware Maker has a specialty to produce high quality plastic gears. Tight tolerances on plastic gears and worms are important for proper function and reduced wear. COVI Hardware Maker can produce high precision plastic gears and worms to meet the standard of customers. Most Gears is applied in the Japanese OA equipment and German tiny motors as well as in the automobile. We can achieve high precision gears according to DIN 58400, module 0.18, quality grade 8f s".
