Stebro Mold is a professional plastic mold maker with in-house plastic injection molding capabilities in China. We specialize in manufacturing high-quality plastic injection molds and plastic injection molded parts for Consumer industries, Industrial industries, Automotive industries, Medical industries, Electronic industries, Agriculture and Gardening industries. From the initial part design and develop stages through final delivery, customer's product quality is our top priority.
Each project begins with a detailed design for manufacturability (DFM) of injection molding report and is reviewed by the experienced toolmaker, mould designers, project manager, and injection molding process engineers. From this report, we will show our customer:
· General Information about Part data such as Part dimension, part weight, plastic material
· General Information about mold data including mold steel, mold shrinkage, feed system, gate type
· Mould Layout and Mould Size
· Gate Locations
· Draft Angle Analysis
· Wall Thickness Analysis, Thick Section, Thin Section, Ribs/Bosses to Wall Thickness Ratio
· Parting lines
· Lifters or slides
· Warp Analysis
· Weld Lines
· Sink Areas
· Surface Finish
· Ejector Pin Locations
· Shut-Off Conditions
· Thin Tool Conditions
then you can see how to optimize part design, our molding manufacturing solution and potentially problematic areas of your plastics parts to minimize tooling costs, reduce design changes, expedite the manufacturing process and ensure part quality.
Mould designs are supported by MoldFlow Analysis, cooling analysis, deflection analysis, and finite element analysis.
Stebro Mold manufactures a wide range of custom plastics injection mould from prototypes to complex final production moulds. Our molds types including:
· Molds with side-action cores and lifters
The common type of side-action is a side-core, which allows the molding of an external undercut. Other devices enter through the end of the mould along the parting direction, such as internal lifter cores, which can form an internal undercut.
· Single Cavity Molds, Multi-Cavity Molds, Family Molds
· Unscrewing Moulds
· Insert Molds
Insert molds bring multiple materials and components together to create a single product. The process can use engineering plastics with metallic materials, which provide strength and conductivity. The insert is placed in the mold, either by hand or automation, before the resins is injected into the mould. As material flows into undercut features in the insert, the insert is anchored more securely than if it were assembled. Vertical injection molding keeps the insert in position during the molding manufacturing process.
· Over Molds
· Gas-Assist Mould
Techniques have been developed whereby inert gas nitrogen is injected into the still molten resin in the mould cavity. Benefits of the gas-assist injection are as below:
Lower clamping force is needed.
Cycle times are reduced.
Less material is used, part weight was reduced.
Improve part strength and rigidity.
Dimensional stability is improved.
Molded-in stress is greatly reduced.
elimination of sink marks and warpage in heavily ribbed parts.
· Two-Shot Molds, 2K Mold, Multi-component injection mold
2K mould is a cost-effective method to produce plastic parts with two or more colors molded at the same time, such as grips, handles and control buttons. Stebro Mold has rich experience in making 2K injection molds.
· Hot Runner Molds
· MUD insert mold
· Prototype molds, Low Volume Plastic Injection Molding Mold
Stebro Mold differs from the other Prototype or Low Volume injection molding companies. We have the experience and equipment to provide unparalleled speed, flexibility and support. We use our exceptional molding expertise to provide comprehensive technical guidance and tooling options for your project. We don’t just send a price estimate for a new project; we send an informed quote after learning about your needs. We pride ourselves on working closely with you from the start, making sure job specifications align with your project’s end goals. We’re also proud of our speed, providing 15-20 business days turnaround on injection mould tooling projects without sacrificing quality or precision.
· High Volume production Injection Molding Mold
Our experienced tool makers use Mikron high-speed CNC machines, Charmiles EDM machines, Sodick slow wire cut machines and Kent grinding machines to build molds that run automatically by the efficient design of ejection, cooling, and delegating systems. We take careful measures and the required steps to ensure your tooling produces high-quality components while maximizing the mould life.
Once an injection mould has run a set number of cycles; inspections, maintenance and cleaning should be performed. Regular maintenance and cleaning improve shot quality, which ensures consistent component quality. Injection mold repairs can be costly, so it is important for injection molds to receive regular maintenance, cleaning, and if necessary, repair, to protect your investment and maintain consistent production. At Stebro Mold, we stand behind our injection mold tooling. As long as the plastic injection mold remains with us we will guarantee that mold for life. There will be no repair or maintenance cost on your injection mold service in China.
We understand yours needs to get your ideas and products to market faster than your competitor. Whether you are looking for a prototype mold in China to get parts quickly, a bridge mold to manufacture parts until your production mold is up and running, or a production mould capable of low or high run volumes, our in-house part design, Rapid CNC prototypes, injection mould design, mould maker, and mold sampling ensures accurate plastic parts with the productivity you need. Having everything under one roof is extremely helpful in providing quicker lead times and keeping everything under our control.
You have to choose the right plastic mold factory from the beginning
There are hundreds of thousands of ISO certificated plastic mold factories spreading over China, some of them are big, some of them are small. The mold price is also different from each mold maker. An understanding of your China mold maker’s capabilities and market is essential to getting the right tool for the job. You have many ways to find your right injection mold maker suppliers.
Having a mold making supplies in the same facility has several advantages:
1, You are able to work with the same project manager “From product concept to manufacturing to assembly to packaging”, reducing lag time in communication between China injection mould manufacturer and injection moulder.
2, The people building the plastic moulds are the same people putting it into the part production. We know the part requirements and mold construction well.. We can give you the best the mold solutions and injection molding process development.
3, Full services In-house plastic injection mold making enables us to reduce downtime and cost when problems arise in production, saving the lead time and money for our customers.
