Holding Technologies
AIM : Air Injection Molding
| Air Technology on mold production / injection molding | |
|---|---|
| Concept | Injection molding through regular AIR |
| Effect | Weight decrease, low-pressure molding(increasing the longevity of the mold), improvement of exterior scratches |
ATM : Angular Pin Trouble less Mold
| Technology to down size the thickness of the mold | |
|---|---|
| Concept | Blowdown and injection molding by decreasing the mold stroke and preventing core damage through decreasing the length of the modified ejector pin |
| Effect | Cost saving of mold, downsized machinery |
GCIM : Gate Cutting In Mold
| Technology for gate cutting production in mold | |
|---|---|
| Concept | Manufacturing technology that automatically removes the gate from the inside of the vessel before the formation after injection molding is completed |
| Effect | Delete processing process after completion of Gate |
HGM : High Glossy Weld-less Molding
| Technology for high gloss mold / injection molding | |
|---|---|
| Concept | Injection molding by heating the mold with steam or heater to produce the product with high gloss exterior |
| Effect | : High glossy exterior, removes spray and painting, improvement of the weld-line |
HWI : Heavy Wall Injection
| Double-shot injection molding of thick products | |
|---|---|
| Concept | Injection molding of thicker material through double-shot injection molding technology |
| Effect | Cost saving of producing molds, increase of molding yield, improvement of contraction |
MASM : Multi AngleSolution Mold
| Technology to remove multi angle under-cuts | |
|---|---|
| Concept | To remove the restriction of the under-cut which is shaped in a multi-angular radiating form during product molding and blowdown |
| Effect | Creates various under-cut structures inside the product when molding |
Multi 3D Cooling
| Technology to create 3D cooling mold | |
|---|---|
| Concept | To create molds with 3D cooling instead of 2D on middle-large molds (over 550ton) |
| Effect | Improved cycle time of molding), improvement of local cooling |
NPM : Nano Pattern Mold
| Technology to form fine patterns | |
|---|---|
| Concept | To form fine patterns by applying lithographic technology on the mold instead of standard mechanical processing |
| Effect | Improved quality of appearance, removal of high gloss lapping/etching, etc |
NTPM : No Taper No Partition Mold
| Non-slope mold / injection molding | |
|---|---|
| Concept | To produce zero sloped product without the application of the slide-core on the exterior of the product |
| Effect | Improved quality of appearance(removal of surface core-line), forming compact, no-slope designs |
TCM(ToC) : Two Color Molding
| Technology on double shot mold / injection molding | |
|---|---|
| Concept | Creating mold and injection molding, using 2Head injection molding device to create dual color or over-molding products |
| Effect | Improved production process(decrease of number of parts), creation of various appearances on the product |
