Transfer & Injection Moulding Presses - Benefits

As the mould is closed before the rubber charge is forced into it, closer dimensional control is achievable. In the transfer process, fresh rubber surfaces are produced & this allows development of a strong rubber-metal bond with any insert in the mould. Unit production costs are lower due to shorter cure times as a result of heating the rubber due to flow through sprue, runner & gates & shorter downtime between guns, as only one charge blank is necessary, even if a multi cavity mould is used. Special screw mechanism preventing rubber strip rupture during feeding. Accurate temperature control at all areas before injection. Some of the benefits of Transfer and Injection Moulding Presses are as follows:
