Question 1

몰드 디자인에 사용할 수 있는 파일 형식은 무엇인가요?

Accepted Answer

The production cycle of plastic injection molding services varies wildly, mainly depending on the complexity of the products.Take a simple plastic stationery clip as an example. The plastic mold design takes 1-2 days, and the production of the simple mold takes 1-2 weeks. For low-volume plastic molding solution(say, 1000 pcs), it takes 1-2 days. Simple quality inspection and post-processing take from a few hours to half a day. The overall cycle is 2-3 weeks.However, for a complex plastic intake manifold of a car engine, the design of the precision mold takes 2-3 months, and the fabrication of the complex mold takes 3-6 months. For large-batch injection molding service (for example, 30,000 pcs), it takes several weeks. Comprehensive quality inspection and elaborate post-processing each take 1-2 weeks. The total cycle may take 6-12 months or even longer.Therefore, the cycle of simple products can be as fast as a few weeks, while that of complex products can last for several months.

Question 2

플라스틱 사출 성형 비용에 영향을 미치는 요인은 무엇인가요?

Accepted Answer

Factors affecting the cost of injection molded products are mainly in the following areas:Product design Complexity: The more complex the shape, dimensional accuracy, functional requirements, the higher the cost, involving mold manufacturing, injection molding process and material selection.Structural design: wall thickness and demolding design affects the quality and productivity, reasonable design can control costs.Appearance requirements: high-quality surface, color and decorative requirements will increase costs.Mold factorsMold type and quality: the number of cavities, materials and precision affect the mold cost and productivity.Mold life and maintenance costs: short life or high maintenance costs will increase costs.Injection molding productionMaterial cost: Material price and wastage rate is an important part of the cost.Production batch size and efficiency: batch size and production efficiency significantly affect the unit product cost.Post-processing and packaging Post-processing costs: processing technology and quality requirements determine the post-processing costs.Packaging costs: materials, design, quantity and method will affect the cost of packaging.

Question 3

Accepted Answer

Our company ensures product consistency during plastic injection molding for high-volume production through the following methods:Raw Material Management1. As an excellent injection molding company, 天美影院 has fixed raw material suppliers.2. We conduct material testing on every batch of raw materials entering the factory and store them in a scientific way.Mold Management1. The mold design and manufacturing at 天美影院 are controlled by relevant standard documents, which can ensure the quality of key processes.2. We have our own mold house. We regularly maintain the molds to reduce deviations.Management during plastic injection molding production1. We strictly control process changes. If there are any changes, we need to conduct thorough verification before adoption.2. We conduct multiple trial moldings internally to obtain the optimal parameter settings for the injection molding machine. Also, there are dedicated personnel to monitor during production.

Question 4

제품 설계 시 고려해야 할 요소는 무엇인가요?

Accepted Answer

When product designers or design companies are designing plastic products, you can consider the following points:Product Structural DesignDemolding Design: You can set reasonable draft angles (0.5° &#8211; 1.5° for outer surfaces, 1° &#8211; 2° for inner surfaces). Please avoid undercut structures whenever possible, and use special mold structures such as slides.Wall Thickness Design: Keep wall thickness as uniform as possible, ideally between 1mm and 4mm. Design ribs reasonably (rib thickness should be 0.5 &#8211; 0.7 times the product wall thickness, with moderate height) to avoid issues like uneven cooling, sink mark, warping, or distortion.Assembly Structure Design: Consider mold manufacturability and injection feasibility when designing assembly structures, paying attention to snap-fit dimensions, strength, and demolding direction, as well as assembly gaps (around 0.1 &#8211; 0.3mm) to prevent interference or looseness.Mold Design ConsiderationsParting Line Design: Choose the largest contour of the product as the parting line to ensure that after opening the mold, the product stays on the moving side for easier ejection and reduces the impact of parting lines on product appearance.Gate Design: Position the gate in areas where the product wall thickness is thicker. Select an appropriate gate type (e.g., side gate, pin gate, submerged gate, etc.) based on the product’s appearance and size. Properly determine the gate size to avoid issues like short shots or flash.Cooling System Design: Design cooling channels close to the cavity surface and evenly distributed, with a distance of about 10 &#8211; 20mm from the cavity surface. This ensures uniform cooling of the product and prevents internal stress and deformation caused by uneven cooling.Material Selection and Performance ConsiderationsMaterial Flowability: Choose materials with suitable flowability based on the product’s shape and structure. Melt Flow Rate (MFR) is a good measure. For complex or thin-walled products, select materials like PP or PA with high flowability.Material Shrinkage Rate: Consider the material’s shrinkage rate and leave allowance for shrinkage. Different materials have different shrinkage rates. For example, ABS has a shrinkage rate between 0.4% and 0.7%.Material Mechanical and Chemical Properties: Choose materials based on the product’s usage environment and functional requirements, considering factors like material strength, toughness, chemical corrosion resistance, and compatibility when parts of different materials come into contact.
