The SprueThe sprue is a round, tapered hole which leads the plastics material from the nozzle of the heating cylinder of the injection molding machine to the distributing runners in the mold. The heater nozzle makes contact with the sprue bushing at the small end of the taper, against some sort of accurately fitting seat which in this diagram is shown to be spherical. The diameter of the small end...

Some mould makers prefer to perform certain rough machining operations on the mould block before the mould undergoes normalizing heating, while others prefer to carry out the latter process immediately after receipt of the steel. Where the former method is adopted, some little care must be taken to insure that adequate amounts of material are left on all important portions so as to allow sufficien...

Injection moulding is used to create many things such as wire spools, packaging, bottle caps, automotive parts and components, toys, pocket combs, some musical instruments (and parts of them), one-piece chairs and small tables, storage containers, mechanical parts (including gears), and most other plastic products available today. Injection moulding is the most common modern method of manufacturin...

Moulding tolerance is a specified allowance on the deviation in parameters such as dimensions, weights, shapes, or angles, etc. To maximise control in setting tolerances there is usually a minimum and maximum limit on thickness, based on the process used. Injection moulding typically is capable of tolerances equivalent to an IT Grade of about 9–14. The possible tolerance of a thermoplastic or a th...

Routine maintenance operations personnel plastic injection mold, the main content of wiping, lubrication and inspection.During production maintenance:1. Production in the corresponding part of the mold on a regular basis were oiled. Such as: drawing die ring binder, rounded; trimming knife mold parts; knife block flange portion and the like;2. Regularly trimming hole punching die to clean up waste...

Cavity Surface roughness: Injection mold cavity surface roughness directly affect gloss products, injection molding mold highly polished surface will be bright surface products, Wu Guang injection mold is prepared dull products. Multi-cavity die too if the surface roughness, the surface of the plastic sheet adheres easily mold cavity, the surface roughness value should be less appropriate injectio...

Design Engineer is very critical in the whole mold developing process. They assess the part design and make modifications and recommendations based on key product requirements including product usage and function. The engineer will need to know:1. How will the part be used? Is it a standalone product or a component of a larger assembly?2.What are the dimensional and tensile requirements?3. Does th...

In general, we select the steel according to the functional of parts :1.For mold base part : 45#、S45C、S50C etc.2.For mold cavity / core: P20、2311、738、738H、718、718H、NAK80、2316、2316H、2083、2083H、S136、S136H etc3. For harden treatment material: 2344、8407、SKD11、SKD61H13、etc.3.For Shaped parts : perhardened steel would be good choice. Such as P20、P5、NAK55、NAK80、738、718、420.4.For cooling parts , choices i...

Medical mould devices are divided into a lot of kinds, some products do not contact with the human body, some contact with the human body, sometimes into the body, is different to the requirement of mould material.According to the nature of your product, no product contamination, determine the mold material, as long as to achieve the purpose of without causing harm users, of course this is at the ...

According to the size of the production capacity, product structure, to determine the appropriate number of cavities, more cavities, precision molds, processing difficulty, the higher the cost of the mold. However, injection molding unit price will decline.Impact of multi-cavity Dimensions factors:1. precision mold machining. For example, the discharge cavity, each cavity is a discharge, if the di...

CNC machining allows customers to have a prototype produced out of the real material instead of a photopolymer or polyamide simulant. From nylon to aluminum, Star Prototype specializes in creating the highest quality CNC prototypes at low cost to the customer. CNC machining is typically used for projects with 50-100 sets of components, as a simulant material is not sufficient for those types of a...

Part line is a typical defects for injection molded parts with many hole features, such as computer key board typically, the hot resin flow around the little inserts and melt flow meet each other on other side where the welding line occurs, this is how welding line occurs, melt flow temperature always drop while melt resin flow over the mold cavity, that is why the welding line can only be optimiz...

Complexity of the mold, including part design, size, and number of cavities and materials used all have major impacts on the overall cost of the mold. Mold costs can range from a few thousand dollars for a simple design to hundreds of thousands of dollars for a complex, multi-cavity, multi-action, hardened steel mold.

Longxiang has the capability to design and build almost any part required for any mold. The majority of our projects are completed fully in-house
