Custom mold & plastic parts, Rapid tooling
|Rapid tooling||Molds with aluminum inserts with a life time of up to 20,000 runs. Machined in typically 2-3 weeks.|
|Production tooling||Traditional hard molds, machined in typically 4-5 weeks.|
|Single cavity molds||Molds containing only one cavity, producing one unit per run.|
|Molds with side-action cores||Cores slide out of the part from the side before it is ejected from the mold. This allows for undercuts to be molded.|
|Multi-cavity molds||Multiple identical cavities are machined into the mold tool. This allows for more parts to be produced per shot, minimizing the unit costs.|
|Family Molds||Several parts are designed into the same mold tool. This allows for the minimization of tooling costs.|
|Insert molding||Inserts are placed into the mold and molding occurs around them. This allows for inserts such as helicoils to be molded in your design.|
|Overmolding||Premade parts are placed into the mold to mold over them. This allows for multi-material injection molding.|
Our injection molding service can move from prototyping to end-part production.
|Minimum order quantity||100 runs|
|Mold material||Tool Steel P20, Carbon Steel S50C, Aluminum|
|Mold types||Rapid tooling, production tooling|
|Mold storage||Minimum 2 years|
|Mold lead time||2-3 weeks (Rapid tool), 4-5 weeks (Production tool)|
|Quality assurance||Inspection reports included, full dimensional report and material certifications available upon request.|
|Design verification program||Similar to First Article Inspection, you will receive 2 sets of parts upon the machining of the mold to test fit before continuing with full production.|
|Mold remachining||We can remachine the molds should any changes be required, changes to be reviewed on a case by case basis.|
|Additional technical support||Dedicated Shunho Plastic Solutions Mechanical Engineer for technical support.|
Available materials for plastic injection molding
All thermoplastics can be injection molded. Some thermosets and liquid silicones are also compatible with the injection molding process.
ABS, Nylon (PA 6), PC/ABS, Polyurethane (PU), Acrylic (PMMA), Polypropylene (PP), Polystyrene (PS), Polycarbonate (PC), Polyvinyl chloride (PVC) and POM (Acetal/Delrin).
|Glossy||A-1, A-2, A-3||The mold is smoothed and then polished with a diamond buff, resulting in parts with a mirror-like finish.|
|Semi-gloss||B-1, B-2, B-3||The mold is smoothed with fine grit sandpaper, resulting in parts with a fine surface finish.|
|Matte||C-1, C-2, C-3||The mold is smoothed using fine stone powder, removing all machining marks.|
|Textured finish||D-1, D-2, D-3||The mold is first smoothed with fine stone powder and then sandblasted, resulting in a textured surface.|
|As-machined finish||The mold is finished to the machinist's discretion. Tool marks may be visible.|
