Plastic office waste dustbin mould design process
SWY MOULD has an experienced design team who are familiar with mold design standards in China, Europe, the United States, Japan, etc. and are able to use various software for mold and product design. We have a mature design process, from part analysis, runner analysis, structure analysis to process analysis, and adopt the full 3D design. We have design capabilities and can design more than 30 sets of complex molds every month.
Our engineers have rich design experience and comprehensive development concepts. Engineers adhere to the principle of “design is the key to the mould” and attach great importance to the mould making process. Elaborate design, trying to create a mold with the longest service life and few maintenance times. Customers only need to provide two-dimensional or three-dimensional renderings or samples in DXF, DWG, PRT, SAT, IGES, STEP, and other formats. We will scan the samples and make a product blueprint. Once confirmed by the customer, the mold can be made according to the customer’s existing project assembly, drawing design.
Tips for injection mould gate design
For mold gate design, there are some tips you have to consider to ensure that the design comes out exactly as you want and serves your purpose.
The following should help you along the way:
1. Avoid obstructions like pins, cores, and sidewalls that may end up impeding the flow of plastic being injected into the mold. Keep gates away from any form of obstructions.
2. Ensure that the area around the mold gate is well strengthened as it will be subject to a lot of pressure and stress. It must be able to withstand all that without collapsing.
3. Consider adding at least two gates for proper filling. If you feel like a second gate is warranted, then add one by all means to enhance the quality of the end product.
4. Prioritize function over aesthetics when designing the gate mold. You can always work on the appearance later, but if the functionality is flawed, then it becomes hard.

We have many years of experience in manufacturing large and medium-sized moulds. From mold design to mould debugging, we provide complete internal services and are your preferred mould manufacturer. We are managed by professionals, staff with complete technology and years of experience. We have many high-end 5-axis machining centers, high-speed milling, CNC milling, EDM, wire cutting machines, and other equipment. We use the latest CAD/CAE/CAM, which not only guarantees the quality of the mould but also improves efficiency.
Plastic office waste dustbin mould quality control system
SWY MOULD relies on a solid mold foundation, introducing advanced quality inspection equipment, to ensure the special and characteristic requirements of each product.
The company has always paid attention to the cultivation of talents. It has a group of high-quality and professional management personnel and technical personnel, which are completed by the consistent operation of an order, development, production, and service; from the audit of raw material suppliers, incoming inspection, and production line products There is a complete and strict quality control system from screening to final product testing.
In SWY company, quality assurance, control, and monitoring procedures as a philosophy run through every aspect. The quality control of our work is reflected in every step of the mold manufacturing process.
1. Mold flow analysis can avoid potential molding problems.
2. Each piece of steel after heat treatment will be rechecked for hardness internally.
3. After processing, each mold part will be measured by CMM before assembly.
4. Check the overall function and structure of the mold before the mold test.
How to make different colors for plastic office waste dustbin?
Plastics of different colors are being used every day, covering a broad range of applications and scenarios, but few people know or consider, how these color hues are created.
A variety of coloring systems can be used to color the plastic materials, each possessing its unique features, benefits, and weaknesses, among which masterbatches, “salt & pepper” blends, liquid color, and pre-colored plastic are the four most commonly applied coloring methods.
We always seek to buy “natural” polymers, e.g. Nylon, LDPE, ABS, and Polypropylene in pellets, to color the plastic injection molded products. After that, we blend the color concentrates we purchase with a dosing unit to get the colorants dispensed anywhere usually from 1% to 4%. To color all of our natural polymers with the exact amount of colorants, the dispensing unit needs to be calibrated and properly set.
The process to match the color:
To guarantee different colors product is colored with the desired hue, we need to complete a color matching process, so as to allow our team of experts to create specific color concentrates for specific applications. Usually, a general idea about the desired color hue can be offered by a chip, plaque, or Pantone number(or RAL number), while the specific formulation for color concentrates can be identified with the help of the information about the specific polymer selected.
To appropriately color match each and every polymer, we need to consider various factors that include viscosity and melt processing temperature. For instance, a lab might need guidelines on the formulation to identify the suitable carrier resins, pigment systems, stabilizers, and other additives for the specific product and application, which might be prescribed on the request form of color match. Also, you need to keep in mind that the gloss level, appearance, and filler content will have an influence on how the color actually looks. For example, the same color looks different on nylon than it is on acrylic. Besides, we need to take such factors as environmental conditions, chemical resistance, and FDA suitability into account during the color matching process.
A qualified colorant supplier should be able to do color matching in any polymer system that might include nylon, polypropylene, polyethylene, polyesters, PVC, and acrylics. With the help of a computer color matching system, colors are measured, stored, and formulated by using a color spectrophotometer. When preparing a color match, the color matching system, as well as chip files or plaques created in a lab will be used to store all the different colors and polymer systems.
