1, filling defect It always show uncomplete filling or edge collapse,it will dective product,waste material,labor and time.ther are many possible reason, such as nozzle temperature is too low,not enough supply,flowablity not good,injection pressure is low,the gate is too small or not right position,the mold surface is not smooth enough,nozzle is blocked,venting problem     2,flash or burr It always happen in parting line,it will increase the difficulty of machining or dishape,even defective.the possible reason such as:nozzle temperature too high,injection too much material,flowbility is very good,injection pressure too high,clamping force too small     3,sink mark It always caused by material shrink after injection molding,possible reason such as:nozzle temperature too high,resin supply not enough,shrinkage is too big,injection molding pressure too low,holding time too short,injection speed too slow,mold teperature too high,cooling time too short,the thickness of pr...

What Is DFM? Otherwise known as Design for Manufacturing. DFM is a process used to optimise the design of a product or part for the most efficient and cost-effective way of manufacturing. DFM is essential for ensuring that designs will function as expected and can be produced accurately and efficiently, reducing production time and cost.   PPS ’s DFM Service At PPS we offer a free DFM consultation service to help us better understand your project requirements.    5 Key Principles Of DFM The DFM process covers 5 key principles; Process, design, material, environment, compliance, and testing.   1. Manufacturing Process For DFM to be most effective you must be sure you are using the right manufacturing process for your project.   For Example… if you need to manufacture a high volume of plastic parts, it’s most likely that injection moulding will be your best option. For detailed metal parts, CNC machining is probably the most appropriate process...

What is Rapid Prototyping? Prototyping is the process of validating the possibilities that a product will be capable of solving the problem that is required to. A prototype seems to be real enough such that potential users can interact with it and give feedback. In case the feedback given by the user about the prototype is negative, the firm is saved considerable amounts of time and money to build a product or service that won’t perform in real sense. Positive feedback, on the other hand, shows that the product concept is on point and from there; and aids in the advanced product development.    The term rapid, on the other hand, is used to mean the speed in which the prototype can be produced. Also, how fast the feedback can be collected and synthesized and also, how quickly the following iterations can go through the same process. Therefore there is a great need for teams to strike a balance between creating a prototype that looks near-real so that users can provide re...

BASIC PRINCIPLES Injection moulding is a formative manufacturing technology, i.e. material is formed from an amorphous shape into a fixed shape defined by a mould tool. Almost every plastic part created today is by injection moulding as it allows identical parts to be created in huge numbers, in a short space of time, and at very low cost per part.   The process works as follows:   1. A mould cavity defines the shape of the part. 2. Material (melted plastic) is injected under pressure into the cavity. 3. When the plastic cools it solidifies to take the form defined by the mould. 4. The part is ejected, and the process repeats from step 2.   Part Creation Whilst the part cost is low, injection moulding has high set up costs, mostly from the cost to make the tools (using CNC) Mould tools range from a few hundred GBP to over 100,000 GBP depending on complexity. The materials used for the tools varies depending on how many parts are to be made and the accuracy required. All ...

Injection molding is an efficient and effective production method that results in quality products. Nonetheless, you need to choose a reliable injection molding partner if you are aiming to gain a competitive edge in the market.    With a reliable injection molding partner, you will be able to cut costs, get better quality products, and have efficiency in the supply chain. Additionally, the partner can help with the myriad choices, options, and challenges that you might be facing.    While the process of choosing an injection molding partner is not as easy, you can focus on a partner based on their technology, customer service, quality control, and sustainability prowess. In this article, we will explore the top 10 injection molding companies.    1.
