Minimize Virgin Material with Sustainable Co-injection PCR Solution
When it comes to Post-Consumer Recycled (PCR) materials and sustainable applications, Mold-Masters has the proven capability. Utilizing the company's industry-leading co-injection multi-layer technology, Mold-Masters have the ability to combine two separate resins into a single 3-layer melt flow. This enables the cooperation to be able to inject high PCR content as the core layer up to 50% of total part weight without sacrificing part quality or cycle time while minimizing virgin material. In the firm's most recent production application, Mold-Masters implemented a co-injection system for producing 5 gal. (20 L) pails. Each of these 700g pails incorporated 50% PCR as the core layer.
PET-Series 2-stage Hot Runner System
Mold-Masters new PET-Series hot runner system delivers consistent high-performance processing capabilities for exceptional preform quality. As always, Mold-Masters is focused on increasing the customers productivity, enhancing reliability, and lowering part costs. The comany's PET-Series hot runner gives the customer the ability to fill thinner preforms (light weighting), to save resin thanks to better HR balance and less variation in preform weight, reduction in cycle time due to faster fill time and a wider process window along with a reduction of AA content.
Mold-Masters achieves this great performance with the industry leading iFLOW Manifold Technology. The firm's proven 2-piece manifold designs incorporate patented melt flow geometry, flow path options and runner shapes that allow the engineers to optimize performance to the customers application. In addition, we are also introducing a new PET-Series Nozzle with improved thermal profile, field replaceable heater sleeve and industry standard gate design. PETSeries nozzles also incorporate new MasterSHIELD Technology for enhanced leakage protection between the nozzle and manifold even during cold start-up.
PET-Series hot runner is compatible with any major brand of PET-preform mold.
New Fusion Series G3 Hot Runner System
Mold-Masters is proud to announce the launch of the new Fusion Series G3 hot runner system. Fusion systems are shipped completely pre-assembled, pre-wired, plumbed and tested for fast, one-step installation. Mold-Masters FusionG3 system incorporates several major enhancements (over the previous FusionG2 system) that helps optimize mold design and simplify/speed up installation. These enhancements include:
- Reduced nozzle bore cut-outs
- New nozzle heater sleeves (optional)
- More compact actuators (PN and HY)
- Room temperature installation
Fusion Series G3 nozzles feature more compact nozzle bore cut-outs to help minimize tooling requirements and are available in customizable lengths up to 1,000mm. Fusion nozzles incorporate field replaceable heater bands and gate seals to ensure molders can respond and fix issues quickly on-site to minimize downtime. Most gate seals are interchangeable between G2 and G3 so customers are able to convert to the new system in many cases without any special retooling. New heater sleeves protect the nozzle and wiring from damage during installation and do not impact cut-out dimensions.
The new compact actuators minimize stack heights with cut-outs that are the same or smaller than G2. Anti-rotation and valve pin disconnect are now standard features. Compact actuators are available as either hydraulic or pneumatic. The position of air/hydraulic lines and cooling lines can be rotated to be set perpendicular or oriented different to one another to allow easier access when space is limited. Headless Valve Pin is a new feature which can be re-worked in the field (steel safe).
FusionG3 also has the advantage that it is engineered to be installed and uninstalled at room temperature. It can be pulled directly from the shipping box and placed into the mold. This helps to significantly reduce installation time, eliminate extra equipment such as a temperature controller and improve safety conditions during installation, assembly and removal.
Mold-Masters Fusion Series G3 hot runner systems are covered with an available industry-leading 5-year warranty.
E-Multi Auxiliary Injection Unit (New EM5 Model)
Mold-Masters is proud to announce the introduction of their largest capacity E-Multi, the EM5. E-Multi is an all electric, servo driven auxiliary injection unit that offers proven precision, repeatability, versatility, and reliability. This new unit extends the capabilities of auxiliary injection units by offering an expanded shot range of 550g to 1,237g (18 to 42 oz). This larger capacity is well suited to the production of large individual components and high cavitation molds. Their EM5 model is expertly designed to meet the processing and capacity demands of the customers larger multimaterial applications across a wide range of industries. Due to its size and weight, the EM5 is intended to be installed in a horizontal configuration as standard however an optional vertical installation package is available.
The proven E-Multi platform is currently installed in over 500 applications globally. E-Multi easily and economically converts any existing injection molding machine to allow for multi-shot, multi-material or co-injection capabilities that can be implemented with significantly lower capital investment requirements and faster lead times than a traditional multi-shot injection machine. E-Multi units are available EM1-EM5 which offers a broad shot range from 7.7g to 1237g (0.26 oz to 42 oz) and is compatible with a range of materials including PCR and Bio-Resins. An E-Multi LSR is also available.
New AXIOM (TG-Thermal Gate) Single-Stage PET Hot Runner System
It’s time to modernize single stage PET bottle production. Mold-Masters new Axiom (TG) hot runner system brings the latest processing technology to enhance molded bottle quality, increase productivity and lower cost per part. AXIOM (TG) is an economical direct replacement to many existing outdated single-stage hot runner systems.
AXIOM (TG) is a newly developed optimized design created to meet the needs of single stage PET molders. It features a new optimized nozzle and gate seal design and incorporates Mold-Masters proven iFLOW manifold technology. The new AXIOM (TG) nozzle offers an excellent thermal profile to deliver precise and repeatable processing capabilities. Axiom nozzles incorporate individual nozzle heaters for individual temperature control which are also field replaceable for quick and easy maintenance. The nozzle also incorporates threaded nozzle base for integrated leakage protection. The gate seal design seals on the face and incorporates an industry standard cut-out which allows for a direct replacement for many common single stage hot runner systems that rely on outdated technology.
New SYMFILL Technology
Significantly Enhance Part Quality by Minimizing Barrel Bow
SYMFILL Technology significantly minimizes core shift to improve part quality (straightness) of cylindrical, centre injected components having an aggressive L/D ratio. It achieves this by allowing the melt to enter the nozzle runner channel from multiple sides as opposed to the single-entry point of traditional designs. Examples of such components that would benefit from this technology include blood tubes, needle shields, over caps and other similar parts from the medical, cosmetic and stationary industries.
Minimizing barrel bow offers many downstream processing advantages which includes:
- Tubes roll concentrically in the labelling machine.
- Increases final stage throughput.
- Minimizes machine downtime.
NEW Cylindrical Hot Valve – CP (CHV-CP) Gate
Mold-Masters introduces a new gate seal engineered to extend gate quality production life and simplify maintenance. Suitable for Packaging and other similar applications it is compatible with Commodity and Polyolefin resins (PP, PE, TPE).
Incorporates Enhanced Pin Guidance
- Funnels the pin to the gate to avoid contacting cavity steel.
- Minimizes wear to maintain gate quality and extend service life.
Features a Replaceable Gate Insert
- Provides molders with an easy to replace component.
- Eliminates traditional gate hole rework/welding.
- Allows for maintenance costs to be much more predictable and minimizes downtime.
Compact Ø3mm OD Tip (1.0mm gate)
- Can fit on a wide range of parts
- Will produce a double witness ring.
- Since tip contouring and texturing is possible the visual impact of the ring can be minimized on the part surface.
