UK machine tool distributor Warwick Machine Tools Ltd. (WMT), founded in 1970 and acquired by Yuasa Trading of Tokyo in 1992 to form Yuasa Warwick Machinery, has been reestablished under the old name as sole UK agent for ONA EDM equipment and a new range of bed-type machining centres from MTE. Both ONA and MTE are based in northern Spain. ONA is the biggest producer of large-scale EDM machines in the European Union and the oldest EDM equipment manufacturer in the world.

This machine is very good for making plastic molds

WMT is a joint venture of Yuasa Trading and Gerard Berger, who was responsible for ONA sales at Yuasa before becoming managing director of the new company. Paul Barry continues as technical director. All warranties on ONA equipment installed in the United Kingdom will be honoured by WMT.

Says Berger: “In reestablishing WMT as essentially a single-product supplier of ONA equipment, albeit we now also have a complementary range of prismatic metal-cutting machines, it is my intention to give ONA customers the support they deserve but that was perhaps diluted when the products were sold through a multi-machine-tool distributor.” Technical sales are handled both in-house and through distributors, with an emphasis on collaborating with the customer to satisfy particular needs.

The company recently unveiled a new range of high-end ONA die-sinkers and fixed-bed submersible wire-cut machines as well as entry-level wire-cut machines based on the Prima family.

Advantages of Hot Runner systems for plastic molds

1) no outlet material after processing is not required, so that the entire molding process is fully automated, saving time and increasing efficiency.

2) the pressure loss is small. Hot runner temperature and the injection molding machine nozzle temperature equal to the raw surface to avoid condensation inside runner, injection pressure loss.

3) outlet material will be reused plastic performance degradation, and use the hot runner system has no outlet material can reduce the loss of raw materials, thereby reducing production costs. Temperature and pressure in the cavity uniform, small plastic parts stress, uniform density, in the smaller injection pressure, a relatively short molding time, better than the average of the injection system of the injection molding product. For transparent parts, thin pieces, large plastic parts or high demand plastic parts can show its advantages, but also can be used to produce a larger product smaller models.

4) thermal spray nozzle using standardized series design, with a variety to choose from a nozzle head, good interchangeability. The unique design of the processing of electric heating coil, heating temperature uniformity can be achieved, and long service life. Hot runner system is equipped with manifold plate, temperature control, etc., compact design, a wide variety, easy to use, stable and reliable quality.

Do you need hot runner mold for your business or your new products? Here I offer you some finally suggestion, if you want your plastic mold to running for over 1 million shot, then we suggest you to make hot runner mold, because this will save your cycle time and save the runner waste, if the mold life requirement less than 0.2 million then we suggestion use could runner, of course this is not always the same it is depending on the part size if part size is over 300 mm, then hot runner will be better option, you can go to our mean website to know more about this.
