In the process of injection molding, a thermoplastic polymer is heated beyond its melting point, turning it from a solid to a fluid that has a relatively low in viscosity. This melt is mechanically injected or pressed into mold that mimics the ultimate shape of the product that will be produced. This what we called injection molding.

So what does an injection molding sink marks means? Why does this happen and how can a manufacturer stop it?

The variation in wall thickness on the surface of injection molded parts, such defect known as sink mark.

Sink marks can appear when the part thickness is too thick for the resin being injected into the mold. They are commonly found in thicker areas as a result of varying cooling rates throughout the part or insufficient cooling while the part is in the mold. Low pressure in the mold cavity or an excessive temperature at the gate through which material is injected into the mold can also cause sink marks.

Sink Mark Causes & Solutions:

1. Inadequate control on molding condition:

• If the depression and shrinkage mark appear near the gate, increase the holding time. When the plastic part has a depression at the wall thickness, the cooling time in the mold should be extended.
• By raising the insert temperature, depression and shrinkage mark can be stopped.
• If the injection molding machine’s nozzle hole is too small or the nozzle is locally blocked, the local loss of injection pressure will result in depression and shrinkage marks. As a result, the nozzle must be replaced or cleaned.
• Surface depression can be fixed by the increased feeding amount

2. Mold deficiencies:

• Sink marks that appear far away from the gate are usually caused by poor melt flow in a specific part of the mold structure, which prevents pressure transmission. In this regard, the structural size of the mold gating system should be appropriately expanded, particularly for the “bottleneck” that impedes melt flow, the sprue section should be increased, and the sprue should be extended to the recessed part.
• Wing gates should be used for thick-walled plastic injection molded parts. In this manner, for plastic injection molding parts that are not suitable for directly setting the gate on the plastic part and are likely to cause residual deformation at the gate after molding, a wing-shaped body can be attached to the plastic part, and the gate can then be set on the small wing. The winglets’ gates can be inverted and point gates, transferring the plastic part’s concave defects to the winglets, and the winglets are cut off after the plastic part is formed.

3. Insufficient raw material for molding:

• The surface of the plastic injection molding part will show depressions and shrinkage marks if:
• the shrinkage rate of the molding material is too high,
• the flow performance is too bad,
• the lubricant in the raw material is insufficient,
• or the raw material is damp.

In order to the greatest extent possible, low shrinkage resin grade should be chosen for plastic parts with high surface requirements.

4. The plastic injection molded part’s structure design is absurd.

• Because of insufficient pressure during molding, thick-walled parts are prone to dents and sink marks if the wall thicknesses of the plastic parts vary greatly. As a result, the wall thickness should be as consistent as possible when designing the shape and structure of injection molding parts. If the wall thickness of the plastic part varies, special cases can be solved by adjusting the structural parameters of the gating system.

There are numerous methods for preventing sink marks in injection molded parts, and understanding how and why they occur is the first step. CADMOULD is one of the effective and potential software for sink marks.

The internet has completely revolutionized the way we do business. It has made communication and collaboration easier than ever before. One of the most important applications of the internet is the online building plan approval system. In order to make the process simpler and to reduce the compliance burden, OBPAS has standardized the process and application form.

Government has envisioned OBPAS to utilize the benefits of information technology to have a single window system for various processes involved in issuance of construction permits of buildings. This system helps in auto approval of all types/categories of plans with “Minimum Human Intervention” to the extent it is possible.

It is capable of analyzing the building plans and generate a set of reports which are comprehensive & easily understandable to all stakeholders.

Some of the key benefits of an online building plan approval system are:

• It Minimize Human Interventions
• It automates the traditional cumbersome paper-based process
• It reads and checks CAD drawings
• It offers a single window for acquiring building permits, NOCs and clearances from multiple agencies
• It enables e-governance while maintaining a digitized version of documents
• It saves time for all the concerned parties by expediting the approval process
• It brings transparency to the overall approval process
• It standardizes the process across the organizational levels
• It provides business intelligence which help in effective decision making.
• It helps in “ease of doing business model”.

How it is been done?

AutoDCR is an innovative online system that helps government bodies approve construction permit requests. It can read CAD drawings and check for compliance with regulations, as well as track proposals with associated documents and site visits. It can also be accessed through mobile devices.

Who is it for?

• Smart Cities

What is BIM? Building Information Modeling, or BIM, is a process that allows for the creation of a digital model of a building. This model can be used to track and manage every aspect of the building’s construction. BIM has been a truly revolutionizing concept for the entire AEC industry, promoting efficiency and collaboration like never before.

How BIM Can Help You with Your Project? Being a systematic blend of processes, policies, people information and technologies, BIM allows professionals to acquire deep insights on several aspects like design, cost, time, sustainability and facility management, among others. In a way, BIM facilitates the entire construction cycle, paving way for higher growth in AEC domain. Here are 5 processes which have been positively impacted by the introduction of BIM:

Design Coordination & Clash Detection: Design coordination and clash detection are two important aspects of the construction process that can be effectively managed with BIM software. Design coordination is the process of aligning the various disciplines involved in a construction project. Clash detection is the process of identifying and resolving conflicts. There are two types of clashes: soft and hard. Soft clashes are easily resolved with a few changes, while hard clashes require major changes and can cause delays, cost increases, and workforce management issues.

Detailed Estimation of material: The 5D BIM Model is capable of accurate generation of BOM & BOQ with its quantity take-off function. This kind of automated cost estimation promises high-grade efficiency and saves time in re-estimation in case the geometry or quantity is changed. The on-screen quantity takeoffs help improve decision-making by eliminating prediction and guesswork from logistics, scheduling, and costing. Planners can use 5D BIM models to communicate about costs due to a detailed and accurate BOM that gets updated in real-time with design changes.

Digital Fabrication & Development of Shop drawing: BIM can be used to efficiently manage and control the design and fabrication process. The digital design flow for fabrication and shop drawing design is more accurate and faster, and has the potential to eliminate design issues. With the help of BIM, designers can identify and eliminate issues at the design stage, resulting in a better final product.

Facility Management:  BIM can store all the information you need for the entire life cycle of a project in a single model. This includes information about facility management, which is vital after a building is handed over. The fact that it is easier for everyone involved to access and coordinate different aspects makes it so information can flow more smoothly and there is less chance for miscommunication. BIM can be used to effectively manage all the systems and components associated with regular maintenance, sustainability and energy efficiency.

When it comes to facility planning, BIM can be used to evaluate various aspects for energy efficiency during the design phase. All the documentation related to several components is present in a single digital model, which makes the work of facility managers easier after the contractor moves out of the picture.

Re-Modeling of Existing Building:  BIM can also help with redesigning an existing building. Using a combination of the original design plans, laser scanning of the actual building, and other innovative practices, an integrated digital model can be created for a redesign. BIM can support as-built models of old buildings and existing facilities and can modernize the entire design and coordination process, bringing every stakeholder onto a single platform. The BIM approach can be used to discover retrofit and improvement opportunities within old buildings, making buildings cleaner, energy-efficient, and easier to manage in the future.

BIM technology is a powerful tool that can help improve the efficiency and productivity of your project. By using BIM, you can manage and coordinate all aspects of your project more effectively, from the initial design to the construction process. In addition, BIM can also help you to create a more sustainable and energy-efficient project. Learn how to use BIM for your next project from our experts today.
