RUNNERLESS WELL PLATE MOULDING
The challenge For years, moulding 96-well plates has been a poor compromise between speed, maintenance costs and product quality.
Manufacturers faced two options. The first was a three-plate mould, which fills the product through multiple injection points. This approach leads to excessive resin waste, long cycle times and significant warpage due to high filling pressure. The second option was a single or multi-drop hot runner. While this eliminates waste, it concentrates stress at the gate locations, resulting in poor quality, increased maintenance costs and core cracking as a result of the high injection pressures required. Replacing these cores is expensive, as they are typically built with conformal cooling solutions.
Drivers
• No waste: Because it’s “direct gated”, there is no runner.
• Less Energy: Because the shot weight is reduced by 1/3, because there is no runner.
• No regrinds required: Enabling 100% virgin material use and eliminating energy for runner regrinding.
• Quality improvement: Identical Wall thickness on each WELL, because gating is on TOP on each WELL with 96 valve gate HR .
• Reduce mould maintenance costs: Less wear in the mould, less risk in breaking mould cores, caused by using todays indirect “side gate” gating technology.
