When all the separated items finish production, we need to put all the items together; it is the preparation for the injection moldings service. In this stage, it will take at least one week, Take IML system as example, When plastic thinwall moulds, high speed injection machine, robot, auxiliary machinery equipments, label ready, we will arrange to make testing and production simulation. At this time, professional engineer is doing need, we need them to establishing the whole project, and testing the project until the whole project is qualified.

Last but not the least, injection moldings service comes to the most vital process. When we defined the whole project is qualified, we will execute the production. Product QC dept will enter this project at this moment; they will control the parts quality,

Avoid any damaged parts or some other not qualified parts enter into the next step. Then regarding the packing step, we will calculate the most suitable carton box for putting more parts in one container. This is one derived service for injection moldings service. But it also saves a lot of cost to customers.

Injection moldings service now becoming more and more popular to plastic production lines. Plastic one-stop service is the trend for now and near future.

Medical Injection Molding for Medical Industries

Medical injection molding refers to a specific manufacturing process, with a specialization in the medical industry. Medical injection molding requires specialized tooling (an injection mold) and an injection molding machine (a.k.a. the molding press). Plastic pellets are melted down into a heated cylinder so that the molten plastic can be injected into the mold in order to form the part. As simple as this may sound, there are many variables in this process that can affect the finished product, so focusing on quality and consistency in the manufacturing process is critical. This type of variation in a medical product could result in whether or not the end product would function properly and this would matter to both the Doctor and the patient as well. This is why the manufacturing process must be seen as a whole.

The injection mold (Definition) – A properly designed mold will be able to maintain a consistent surface temperature to assure that every shot of plastic injected into the mold will be done under consistent conditions. A variation in mold temperature may cause the plastic to shrink or fill out differently, resulting in a slight variance in the molded product from piece to piece. Once again, in many cases this variation might not matter, however, when making an injection molded part for a medical application, this variation can make all the difference in the world.

The injection molding machine – The cycle of the machine must be optimized in such a way that it is steady and able to maintain consistent parameters from cycle to cycle. Most modern machines today are capable of meeting this requirement and if the injection mold is designed correctly, the parts will be able to eject from the mold without human intervention so that the machine can be set up for an automatic cycle.

Sino Package Mould Company are specialized in various package and medical mould, in the same time we are professional in various medical mould which are used in hospital, we are the famous mould company for PET testing tube moulds, and Petri dish mould…as because our mature hot runner system for PET and PS injection, also because of our precise machining equipments, process and managements, we are successfully in making high cavities Nr. medical moulds.
