How to evaluate Hot Runner Cost
Evaluating the cost justification for a hot runner mold requires careful consideration of cycle time, material type, annual volume, available press size and power consumption, […]
This kind of hot runner system can greatly increase production efficiency
A new nozzle design developed by an certain mold builder abandons the usual round opening for a wide slit to allow for up to 25% faster cycle times, lower shear and injection pressure. […]
Advanced valve gate technology in hot runner system
Despite some thermal gating (hot tip gating) drawbacks, a number of mold builders still prefer thermal gates for high-cavitation molds. […]
Curved hot runner manifold channel design
Hot runner manifold channel designis essential for the operation of an injection mold, impacting change-out time, part quality and even the number of possible drop locations in the mold. The key to advancing manifold design is having the ability to manufacture and implement curved channels in blocks of steel. […]
How to design a hot runner system for a mold
Creating the most effective hot runner system design that includes manifolds, nozzles and full hot-halves demands a collaborative approach among the moldmaking supply chain: mold builders, molders, original equipment manufacturers and technology suppliers. […]
How to Evaluate a Hot Runner System
Mold builders and injection molders have different requirements when it comes to hot runner systems. Mold builders are often concerned about price, delivery and quality, while the molder is concerned with operation, performance and ease of maintenance. […]
How to maintain hot runner system
Working on hot runner manifolds requires certain skills and training because of the heat expansion of the steel plates and components. If the mold and repair technician does not understand and cannot account for these effects, he or she may have trouble with mechanics, safety and effective processing. […]
Hot Runner System Design Standard is very important
Keeping hot runner system costs down is key to efficient injection mold design. Designing standard items into a hot runner system or hot half can help reduce initial material costs and downtime, simplify spare parts ordering, increase design flexibility and system reliability, ease maintenance, and improve product delivery and quality. These standard items include parts [...]
The advantages of multiple-gate-nozzle hot runner system
Incorporating multiple-gate nozzles means smaller molds, small presses, a balanced fill rate, reduced residence time, temperature control and design flexibility. […]
Valve gate hot runner technology will innovate mold design
Valve gate hot runner technology produces better-quality plastic parts and faster cycle times by offering the most accurate gate control available. Valve gate systems are also an essential tool for automated injection molding because they enable faster mold start-ups, a wider processing window, and clean gates with no stringing or drooling of melt.
