Mini-moulder saves costs on small parts
At a time when keeping manufacturing costs down is crucial - here's news of a machine which will guarantee significant cost savings to injection moulders.
Injection moulding facilities were introduced in 2004 and operate within the company's clean rooms which conform to a general standard of class 10,000/100,000.
MCP's 12/90 VSP MiniMolder, a vertical clamping, pneumatic machine for insert or over moulding is used to mould clear, polycarbonate hubs and polypropylene buttons onto the canulae and stylettes of epidurals and spinal needles.
Colour coded tool inserts are accommodated in multifunction, two cavity tools and correspond to the button colours which denote the gauge or diameter of the canulae, the smallest being just 0.42mm.
The total shot weights for the button and hub tools are 1gm and 2gm respectively.
The 9-tonne clamp force machine incorporates a sliding and rotating mould carrier and insert loading and unloading takes place during the moulding cycle to optimise processing time and increase efficiency.
A key reason NCC's Managing Director, Keith Wakelin, specified the 12/90 VSP Minimolder was its ease of use.
The PLC control panel, with a memory for up to 25 moulding "recipes" features a touch screen for easy setting up of all mould parameters.
Tool changes on the VSP take only five minutes and material changes as little as ten, which significantly reduces downtime.
Mr Wakelin is also impressed with the machine's excellent repeatability, achieved through the screw plasticising and plunger injection controlled by linear transducers.
NCC also moulds a polypropylene, wing shaped 'grip' which can be snapped on to the needle hub if required.
This 0.5gm component is moulded using a 4-impression tool on one of MCP's 12/90HSP horizontal MiniMolders, using the machine's integral hot tip to achieve runnerless moulding and significantly reducing waste and component handling problems. Request a free brochure from MCP Tooling Technologies ...
