GHA for Molds

When it comes to injection moulds and forming tools, surface performance is everything. GHA® hard anodising treatment with silver ions, combined with the patented technologies of Servizio srl of the Rivi Group, transforms aluminium moulds into high-performance tools, delivering measurable advantages at every stage of the production process.

GHA Europe s.r.l. is proud to collaborate with the Rivi Group, one of the leading specialists in the plastics processing sector, to bring this innovative surface treatment directly to the mould industry. This partnership combines GHA®'s patented anodising technology with the Rivi Group's deep expertise in plastic injection technologies and mould manufacturing, offering customers a complete and cutting-edge solution.

​

Why choose GHA® for your moulds?

The combination of a hard anodic oxide layer (500–550 HV) and silver ions (Ag⁺) gives aluminium moulds designed and built using Rivi Group technologies a unique set of properties that directly impact productivity and cost efficiency. The benefits include:

​

• Greater wear resistance — significantly extends mould service life

• Reduced moulding cycle times — faster production cycles

• Easier part ejection — reduced friction on mould surfaces

• Use of lower-tonnage presses — less stress on equipment

• Fewer injection points — simplified mould design

• Lower energy consumption — more efficient production

• Quick and easy cleaning — less machine downtime between cycles

• Lightweight — easier to handle and maintain

• Lower material and machining costs compared to steel moulds

• Corrosion resistance — optimal protection during storage

 

A smart choice for modern manufacturing

Moulds built using Rivi Group technologies and treated with GHA® are already in use in the production of plastic components for the automotive, consumer goods, and packaging sectors. The self-lubricating effect of silver ions reduces the need for release agents, while the antibacterial properties make GHA® ideal for moulds used in food and pharmaceutical applications.​
