This injection mold making project is an electrical switch plastic holder, the material is PC-ABS.

Basic part information

• Part size: 47.64 x 73.59 x 16.59 mm
• Plastic material: BAYBLEND FR3010
• Finish: VDI-18
• Color: black
• Production volume: 10K

Welding lines are 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 optimized but can not be completed removed if you simply use higher mold temperature, in some other cases, changing gate position would just change the welding line to a less critical location, but for a product similar like computer key board, neither mold temperature or changing gate location would work, as a consumer product, the surface finish is quite critical thing, so as you can see now most of the key board product was painted nicely to cover the welding line defects.

Recently JAVE Mold made an injection mold for unmanned aerial vehicle (UAV) frame, here is the UAV's plastic body making process.

Basic part information
Plastic frame:

• Part size: 92.1X92.1X27.35 mm
• Plastic material: PP
• Finish: EDM
• Color: Grey
• Production volume: 20K

Plastic cover:

• Part size: 90x45x10 mm
• Plastic material: PP
• Finish: EDM+Print
• Color: White+Grey
• Production volume: 20K

Considering the UAV industrial demands, estimate annual production capacity will be 20K or more, in order to avoid mass production capacity shortage, not like low volume injection molding, JAVE Mold manufactured separate molds for each part.

This injection mold making project is about a battery tube related product for a US company, this article will help you to understand fully how JAVE Mold help you to bring your design into mass production.

JAVE Mold are engaged in injection mold making for plastic packaging housing/cases in packaging industrial, usually plastic packaging housing/cases are made in PS or PC, with high polish surface, which required SPI-A mold surface finish, most common choices for steel are NAK80, 1.2083, 1.2344.

Injection mold making is a customized process, JAVE Mold engineers work closely with customer to understand their requirements and make proper solution to achieve the best possibility,we are not simply a mold manufacture to deliver the parts according to design, we offer solutions and deliver satisfaction.

From this project, you can see the product designs from customers are not always the optimized one, sometimes the defects of the molded parts are caused by product design problem, the purpose of DFM analysis made by JAVE Mold is to avoid such defects before mold making.

Recently we had done a succeed mold and molding project for a US company, it's a type of a remote controller, project went smooth but I would like to summarize it and point out a few key points, first we take a look on the project.

It's consisted with front case, back case, cover, and silicone pad, there is a BOM for the whole product, but due to Non-disclosure agreement, we can't give more details how it was designed.

Basic part information:

• Part size: 80x45x30mm
• Plastic material: ABS /silicone
• Finish: SPI-B-2
• Color: blue/black
• Production volume: 10K

We made one 1+1+1 family mold for the front case, back case, cover, actually the front case and cover are in blue, back case is in black, the question is how to do 2 different color in one mold? -- we design a turntable gate so we can mold one color by sealing the other cavities, by this way we only need one mold, even the molding productivity is a little lower but given the cost of an extra mold and only 10K production volume, this is still an economic way to go.

Plastic injection molded parts have many applications on architecture industrial, such as PVC water pipes, plastic gliders on windows, shelf support, hangers, handles etc. JAVE Mold has rich experiences to help customer to customize their own architecture plastic parts.

Here is an example to show you how we work with a North American company from mold design to injection molding production for a glider/slider on windows step by step.

Basic information
Glider size: 0.6x0.5x0.3 inch
Plastic material: PA66+GF30
Finish: SPI-B-2
Color: nature
Demand volume: 10K-20K/ year
