Hot runner manifold design
Hot runner manifold is the key part of the hot runner system, the quality influence the injection moulding of products.
About the hot runner manifold design, there are many points to attention. especially the balance.
1) The heat balance of the manifold
The heat balance mainly refers to whether the heating device on the manifold provided by the hot runner supplier is evenly distributed.
2) The balance of manifold runner
The runner balance of the manifold is the primary consideration for the hot runner designer, which is important, and whether the distribution of runner is uniform and directly determines the molding quality and cycle of the mold product. For multi-cavity products,This is the value of the problem, at this time each gate is an independent product, the strict sense is to require absolute balance
