The inherent toughness of ABS enables it to absorb energy during impacts, minimizing the risk of fracture or breakage.

Injection Molding Process

The injection molding process involves several crucial steps that ensure the successful production of ABS parts. Let’s examine these steps in detail.

Clamping: The first step in the injection molding process is clamping, where the mold halves are securely held together by the clamping unit of the machine. This ensures precise cavity alignment and prevents any leakage during subsequent stages.

Injection: The molten ABS material is injected into the mold cavity through the nozzle and the sprue, guided by the injection unit of the machine. The pressure and speed of injection must be carefully controlled to achieve optimal results.

Cooling: After injection, the mold is cooled to solidify the molten ABS material. The cooling process must be properly managed to ensure uniform cooling and prevent warping or other defects.

Ejection: Once the part has cooled and solidified, it is ejected from the mold using the ejection system. Proper design of the ejection system is critical to avoid damage to the part or the mold.

Design Considerations for Injection Molding ABS

Designing for injection molding ABS requires careful consideration of various factors to ensure successful manufacturing. Here are some key design considerations to keep in mind:

Wall Thickness: Maintaining uniform wall thickness throughout the part helps prevent defects such as sink marks and warping. Ideally, a consistent wall thickness of 2-4 mm is recommended for ABS injection molding.

Draft Angle: Incorporating draft angles (typically 1-3 degrees) on vertical surfaces allows for easy ejection of the part from the mold, reducing the risk of damage.

Ribs and Bosses: Ribs and bosses provide structural support to the part. Proper design and placement of these features ensure adequate strength without compromising moldability.

Gate Design: The gate is the entry point for molten ABS material into the mold cavity. Selecting the appropriate gate type and location is crucial for achieving optimal filling and minimizing part defects.

Venting: Proper venting is essential to allow for the escape of air and gases during the injection molding process. Insufficient venting can lead to trapped air pockets, resulting in surface defects such as bubbles or voids.

Surface Finish: Consider the desired surface finish for the ABS part. Smooth surfaces may require additional polishing or texturing of the mold to achieve the desired outcome.

Injection Molding ABS: Best Practices

To achieve optimal results in injection molding ABS, it is important to follow best practices throughout the entire process. Let’s explore some key areas of focus:

Material Selection and Preparation: Choose the appropriate ABS grade for your specific application. Different ABS grades offer varying properties, such as high heat resistance, improved impact strength, or enhanced chemical resistance. Additionally, ensure that the ABS material is properly dried before injection to prevent moisture-related defects.

Machine Selection and Setup: Selecting the right injection molding machine is crucial for successful ABS production. Consider factors such as machine size, tonnage, and capabilities to meet the specific requirements of your project. Proper setup of barrel temperature, injection speed, and pressure control is essential to achieve consistent results.

Mold Design and Optimization: Collaborate with experienced mold designers to create an optimized mold for ABS injection molding. Consider factors such as mold material, runner and gate design, cooling channel layout, and parting line placement. Each element plays a vital role in achieving quality parts with minimal defects.

Process Optimization and Troubleshooting: Continuously monitor and optimize the injection molding process to ensure consistent quality. Adjust parameters such as melt temperature and viscosity to achieve the desired flow characteristics. Conduct cycle time optimization to maximize production efficiency. In the event of defects, troubleshoot and identify the root cause to implement effective solutions.

Common Defects and Solutions: Understanding common defects that can occur during ABS injection molding enables proactive problem-solving. Sink marks, caused by improper cooling or insufficient packing, can be addressed by adjusting cooling or packing pressure. Warpage can be minimized through appropriate mold and cooling design. Flash can be reduced by optimizing clamping force and improving mold alignment. Voids can be mitigated by adjusting injection pressure and temperature settings.

Post-Injection Molding Considerations

Once the ABS parts have been successfully injection molded, there are additional considerations to ensure product quality and adherence to specifications:

Secondary Operations: Depending on the application, secondary operations such as part removal, trimming, and surface finishing may be required. Carefully remove parts from the mold to avoid any damage or deformation. Finishing processes like polishing, painting, or assembly may be necessary to achieve the desired final product.

Quality Control and Inspection: Implement stringent quality control measures to ensure dimensional accuracy and structural integrity of the ABS parts. Conduct visual inspections to identify any surface defects. Perform mechanical testing to evaluate the strength, impact resistance, and other mechanical properties.

FDM – Fused Deposition Modeling

/in /by

Fused deposition modeling, or FDM, is a rapid prototyping technology (aka rapid manufacturing) and is used to convert CAD drawings into physical parts. FDM Prototypes produce ABS Plastic Prototype Models, which have high strength and durability. For a full list of different Rapid Prototyping Technologies including FDM.

How FDM Works

The FDM fused deposition model process is additive which extrudes material in layers. A plastic filament is melted and extruded through a heated nozzle. The nozzle moves to produce a profile of the part then moves down and the next layer is built on top until the entire prototype model is fully built. The model is complete and requires no hardening. FDM is an excellent choice for any 3D Model that needs to closely represent the final product in strength and durability. We are currently using ABSplus material. CAD Models can be produced in about 24 hours depending on the size and complexity. Online price quotes are available for FDM parts.

FDM requires support during the Prototype Model building process and can increase the build time, parts such as architectural models can be built with the 3DP 3D Printing Prototype method which uses not support. Complex models with overhangs are not a good fit for FDM Fused Deposition Modeling.

How to Improve Plastic Injection Products Bubbles Issue

/in /by

Bubbles issues are also know as vacuum bubbles, in which gases are very thin. In general, if the bubbles happen at the moment when you open the moulds, the bubble is a matter of gas interference. Vacuum bubbles are formed, because the plastics fillings are insufficient or pressure is low. 

Solutions
(1) Increase injection volumes; adjust injection speeds, holding pressure and temperatures of injection materials; increase the moulds’ temperature to improve short shots of the products.
(2) Place the pouring gate at the thick part of the workpiece; improve flow conditions of nozzles, runners and pouring gates; reduce consumption of flow.
(3) Improve exhaust conditions of the moulds.
(4) Avoid great differences of the products’ wall thicknesses. 
(5) Improve structures of injection molded products to avoid great differences of the cavities’ parts which can be filled with molten plastics.
(6) Reasonably adjust the molding process to avoid impacts on the plastic moulded products due to gases generated by plastic degradation.

Size changes of plastic products are caused by different shrinkage of the plastics essentially. Any variable operation of material temperatures, molds, pressure and production cycles will lead to size changes of plastic products, especially for products made of materials such as PP, PE, nylon, etc. which have larger crystallinities.

The main reasons are as follows.
1. Machines
(1) Select machines with the large plasticizing capacity if the plasticizing capacity is insufficient.
(2) Check whether voltage fluctuates, components of injection systems wear or hydraulic valves have problems or not, when feeding instability happens.
(3) Check whether motors have problems, screws and charging barrels wear, hydraulic valves are stuck, or voltage is stable or not, when instability of screw speed happens.
(4) Temperature is out of control; proportional valves and general pressure valves are not working properly; back pressure is instable.

2. Moulds
(1) Moulds should have enough strength and rigidity; we should adopt wear resistant materials for the cavities.
(2) When dimensional accuracy is high, we should try not to use a multi-cavity mould.
(3) Ejection systems, pouring systems and cooling systems should be set reasonably so as to ensure stability of production conditions.

3. Plastics
(1) A mixture of the new material and the reworked material should be consistent.
(2) Dry conditions should be consistent; particles should be uniform.
(3) Take into full account the impact of shrinkage on dimensional accuracy.

4. Processing
(1) The higher the temperature is, the smaller the changes of products’ sizes will become.
(2) The mould temperature should be lower when it comes to crystalline plastics.
(3) The moulding cycle should be stable without too much fluctuation.
(4) Shot weight of injection mold products should be stable.
