- Ever Rich Fountain: From airless pump bottles made of PP and PETE to extrusion molding bottles
Ever Rich Fountain Co., Ltd. (ERF) based in Taichung, Taiwan, is a leading Taiwanese manufacturer of premium-quality cosmetics packaging. In addition to locally produced injection molding machines, the company uses injection molding technology from Wittmann Battenfeld on its production floor.
Ever Rich Fountain: all-in-one supplier of packaging solutions
ERF, established by the two brothers Mini and Max Liu in 1991, is today with its 110 employees one of the leading cosmetics packaging manufacturers in Taiwan. As an all-in-one supplier of packaging solutions, ERF offers its customers worldwide a complete service portfolio including counseling and design, as well as mold technology, production and printing of the products, using technologies such as metalizing, vacuum anodizing, hot stamping, screen printing, UV varnishing or soft-touch coating.
From airless pump bottles made of PP and PETE to cream jars
The company’s product range includes Airless pump bottles made of PP and PETE, double-walled Airless bottles, lotion dispensers, PETG and PP extrusion molding bottles , PP and PETE cream jars, pipettes and many other items in a variety of colors and shapes. Its main product line is Airless bottles. These were developed in-house by ERF. The technology of this product enables 100% removal of the liquid from inside the bottle. Consequently, these bottles are used primarily as packaging for lotions in the top price segment.
High-precision parts for dosing pumps produced on MicroPower series
In 2012, Wittmann Battenfeld established business relations with ERF with the MicroPower, its machine series specially designed for injection molding of micro and nano parts. Today, ERF makes high-precision parts for dosing pumps in cosmetics bottles on two machines from the MicroPower series with 150 kN clamping force. The reliability of this machine model, with whose two-step screw-and-plunger injection unit thermally homogeneous melt is injected with shot volumes ranging from less than 0.05 up to 4 cm³, high process stability and short cycle times, has convinced ERF. The machines are equipped with a W8VS2 Scara robot from Wittmann as well as Wittmann temperature controllers and dryers.
“With a single MicroPower, we have achieved the output of four standard machines previously used in this area”, says Mini Liu, Owner-Manager of ERF.
One of the vital factors for ERF in its decision to invest in the multi-component system from Wittmann Battenfeld was the engineering support provided by Wittmann Battenfeld Taiwan and the team from Kottingbrunn, according to ERF.
2-component technology for the production of cream jars
In December of last year, ERF added a hydraulic multi-component machine from Wittmann Battenfeld to its equipment. It is an HM 240/525H/525S with a vertical rotary unit. The multi-color machine is used in the production of PMMA cream jars. The outer layer of plastic is crystal-clear, the inner layer is pre-dyed, in order to create a piano finish effect. Mini Liu explains that this technology offers a number of major advantages compared to the previous varnishing of the cream jars by an external service provider. In this way, both transport damage to these sensitive products and down-stream finishing with chemical varnish can be avoided.
Significant reduction in cycle times
The 2-component technology also enables a significant reduction in cycle times in contrast to injection molding of a single thick-walled part from one component, and consequently a much higher output. ERF acts as a pioneer in the production of cream jars in 2-C technology. Mini Liu regards the production of cream jars with this technology as a pilot project, with more products to follow if this project proves successful. The improvement in product quality combined with the reduction in cycle times, which enables shorter delivery times, constitutes for Mini Liu a major step towards a significant increase in market shares. In addition to the 2-color products, crystal-clear containers are to be produced on this machine as well.
