It is also production process mainly used in domestic plastic pallet mould maker. Plastic pallet produced by injection moulding is characterized by smoothness, smoothness and reasonable structure. In general, molded plastic pallets for injection molded structures are mostly one-shot injection molded. Plastic pallet of this structure has strong impact resistance, is not easily bent and deformed. In some large-sized plastic pallet mold, such as 1600*1400 size plastic pallets, due to large size span, one-shot molds are difficult to achieve, which results in a double-sided welded plastic pallet. Moreover, in some molded plastic pallets with double-sided flat structures, welding pallet often appear. Unfavorable structure of such a pallet makes it easy to open weld during long-term frequent turnover operations.

Low volume injection molding finds application across a wide range of industries where precision, flexibility, and cost-effectiveness are paramount. Some of the key industries utilizing low volume injection molding include medical, telecommunications, consumer packaging, and more.

D, Strong carrying capacity. Because high-strength blow molded plastic pallets is reasonably designed according to force, and actual running condition is simulated by computer engineering analysis, so that bearing capacity of product is strong, evenly distributed bearing capacity is: static load 5~6t, dynamic load 1~ 2t, overhead load 0.7~1t.

Consider the anticipated production volume for your project. Low volume injection molding is typically suited for production runs of fewer than 10,000 pieces, making it ideal for smaller quantities. Thermoforming, on the other hand, offers flexibility for both low to mid-volume production runs, with the ability to scale up or down as needed.

Evaluate the complexity of the parts you need to manufacture. Low volume injection molding excels in producing parts with intricate details, tight tolerances, and complex geometries, making it suitable for applications requiring high precision. Thermoforming is better suited for larger parts with simpler geometries, although pressure forming techniques can achieve finer details compared to traditional vacuum forming.

C. Because air pressure in blow moulding process is same as pressure radiation, it is impossible to completely control reinforcement of corners.

After cooling, the mold opens, and the newly formed plastic part is ejected. Depending on the complexity of the part and the requirements of the project, secondary operations such as trimming, machining, or assembly may be performed to achieve the final desired product.

Surface of injection molded parts is bright, but surface of blow moulding and rotomolding is uneven. Compared to rotomolding, blow moulding has a blowing port. This is a general comparison. I wonder if you can understand it!!!

Low volume injection molding offers several distinct advantages that make it a preferred choice for small to medium-sized production runs:

B. Safety performance is good. Surface of product adopts special anti-skid pattern design, which is safe and non-slip, and can be set with special rubber sliding pad to ensure stability of pallet stacking code. It does not support combustion, conduct electricity, generate static electricity, and it is non-slip, has no burr flash, has no other auxiliary connections to ensure safety of goods and operators.

E, Long service life. Product is formed by a variety of high-strength HMWHDPE plastic compounded materials, high strength, strong impact resistance, and improved outdoor life through a variety of material formulations. It can be used for more than 5 years under normal conditions; 2 to 3 years in harsh environments. Its service life is 5~7 times of wooden pallets, 2~3 times of steel pallets; 3~4 times of injection molded plastic pallets.

Thermoforming often utilizes lightweight aluminum molds, minimizing both tooling costs and lead times. Thermoforming molds are typically single-sided and can be fabricated more swiftly due to the material's malleability, making it an efficient and cost-effective alternative to traditional injection molding.

A. Blow molded plastic pallets is made of high-strength high-molecular-weight polyethylene (HMWHDPE). Plastic is the best environmentally friendly product because of its good viscosity, good toughness, aging resistance, corrosion resistance and pollution-free.

At present, methods for determining shrinkage ratio (forming shrinkage + post-shrinkage) of various plastics are generally recommended in German national standard DIN 16901. That is, when mold cavity size is 23℃ ± 0.1℃ and placed after molding for 24 hours, difference between corresponding injection molded parts measured at a temperature of 23℃ and a relative humidity of 50 ± 5% is calculated. Shrinkage ratio S is represented by following formula: S = {(D – M) / D} × 100% ; (1), while: S – shrinkage ratio; D – mold size; M – plastic part size. If mold cavity is calculated according to known plastic part size and material shrinkage rate, it is D=M/(1+S). In order to simplify calculation in mold design, mold size is generally obtained by following formula: D=M+MS; (2), If a more accurate calculation is required, following formula is applied: D=M+MS+MS2; (3) However, when determining shrinkage rate, since actual shrinkage rate is affected by many factors, only approximate value can be used. Therefore, calculation of cavity size by formula (2) also basically satisfies requirements. When manufacturing mold, cavity is machined according to lower deviation, core is processed according to upper deviation, so that it can be properly trimmed if necessary. Main reason why it is difficult to accurately determine shrinkage rate is that shrinkage rate of various plastics is not a fixed value but a range. Because shrinkage rates of same materials produced by different molding factory are not same, even same batch of same material produced by a molding factory has different shrinkage rates. Therefore, each molding factory can only provide users with a range of shrinkage of plastics produced by its’ own plant. Secondly, actual shrinkage during forming process is also affected by factors such as shape of molded plastic pallets, mold structure and forming conditions.

1. Process is different, blow moulding mean injection + blowing; injection moulding mean injection + pressure; rotomolding mean extrusion + pressure; blow moulding must have head left by extraction of trachea, injection moulding must have a gate section, rotomolding must be cut without shaving

G, Low maintenance costs. High-strength blow molded plastic pallets do not need to be repaired and maintained, even if appearance is damaged, as long as internal columns are well bonded, it will not affect normal use.

Consider the material requirements for your parts. Both low volume injection molding and thermoforming offer versatility in material selection, with a wide range of thermoplastic resins available. Evaluate factors such as material properties, performance requirements, and cost to determine the most suitable material for your application.

The low volume injection molding process begins with the creation of a custom-designed injection mold. The mold is then mounted onto an injection molding machine, where thermoplastic pellets are fed into a heated barrel within the machine, where they are melted to a liquid state. The molten plastic is then injected under high pressure into the mold cavity, conforming to its shape and intricacies.

In contrast, low volume injection molding often employs aluminum molds, operating at lower pressures to safeguard against mold damage. This strategic choice significantly reduces tooling costs by 5 to 25 percent, with aluminum's malleability facilitating quicker mold creation, thereby expediting the overall injection molding process timeline.

This approach not only reduces initial investment but also enhances the overall flexibility and scalability of the thermoforming process, making it well-suited for low to mid-volume production runs.

Compare the tooling costs and lead times associated with each method. Low volume injection molding typically requires the fabrication of aluminum molds, which offer cost savings and shorter lead times compared to steel molds used in traditional injection molding. Thermoforming molds are also cost-effective and can be fabricated more swiftly due to their single-sided design and lightweight materials.

Thermoforming boasts several advantages that make it an attractive plastic manufacturing method for low- to mid-volume production:

Consider your project timeline and production speed requirements. Thermoforming typically offers faster lead times and shorter production cycles compared to low volume injection molding, making it a preferred choice for rapid prototyping and quick-turn projects. However, if precision and tight tolerances are critical, low volume injection molding may be the better option despite longer lead times.

Today we are talking about difference between blow moulding pallet and injection molded plastic pallets. Obviously we can literally see that difference between blow molded plastic pallets and injection molded plastic pallets lies in difference in production process. However, due to different production processes, final blow molded plastic pallets and injection molded plastic pallets are different in performance. Let’s first understand pallet mold difference between blow moulding process and injection moulding process.

HEYA is a professional design injection mould company with a series of advanced processing, numerical control equipment, a set of advanced CAD/CAE/CAM technology, and in the field of daily necessities mold has a set of unique experience.

Manufacturing process of hollow blow pallet mold makes up for shortage of weld molded plastic pallets due to large size and specifications. In domestic blow molded plastic pallets, large size specifications are more common. Moreover, production process of hollow blow moulding is relatively advanced, raw materials used are less than raw materials of injection molded plastic pallets of same specification, and will have advantageous advantages in future development of plastic pallets for pallet mould maker. However, due to limitations of manufacturing process, blow molded plastic pallets structure is mostly a two-way fork, which affects flexibility of use. However, with continuous advancement of production process, a series of plastic pallet with single-sided blow moulding structures have emerged, which can realize use of four-way forks for convenient turnover.

Characteristic of thermoplastics is that they expand after heating, shrink after cooling, and of course volume will shrink after pressurization. In injection moulding process, molten plastic is first injected into mold cavity. After filling is completed, molten material is cooled and solidified, shrinkage occurs when injection molded parts is taken out from pallet mold. This shrinking is called forming shrinkage. When injection molded parts are taken out from pallet mold until they are stable for a certain period of time, size will still change slightly. One change is to continue shrinking, this shrinkage is called post-shrinkage. Another variation is that some hygroscopic plastics swell due to moisture absorption. For example, when moisture content of nylon 610 is 3%, dimensional increase is 2%; when water content of glass fiber reinforced nylon 66 is 40%, dimensional increase is 0.3%. But main role is forming shrinkage.

In China, production of molded plastic pallets mainly consists of two processes: injection moulding and hollow blow moulding. Due to difference in production process and difference in production equipment, price of molded plastic pallets, suitability of turnover work, and service life of molded plastic pallets are different even if molded plastic pallets of these two processes are of same specification and same load for pallet mould maker.

Thermoforming is a versatile manufacturing process involving the heating of large plastic sheets until pliable, which are then shaped around a custom-fabricated aluminum tool.

Take into account the size and weight of the parts you need to produce. Thermoforming is well-suited for forming large parts with minimal material thinning, making it ideal for applications requiring lightweight yet durable components. Low volume injection molding can also accommodate a range of part sizes but may be more suitable for smaller, more intricate parts.

(Note: It can only be made in one piece, and welding cannot be effectively performed due to narrow cross-section performance.)

Low volume injection molding, also known as "short-run manufacturing," serves as the vital bridge between product prototyping and high-volume production, catering to orders typically fewer than 10,000 pieces.

Advanced Plastiform offers guidance on the optimal manufacturing process to maximize efficiency and cost-effectiveness for low run, plastic parts.

F. Low transportation costs. High-strength blow molded plastic pallets is light in weight and can greatly reduce cost of container cargo transportation. When conducting foreign trade, it is not necessary to carry out fumigation and disinfection by health and quarantine department like a wooden pallet.

Vacuum forming involves suctioning out the air between the plastic sheet and the tool to ensure a snug fit, ideal for larger pieces with less intricate details. Conversely, pressure forming utilizes highly pressurized air to blast the plastic sheet while simultaneously applying vacuum suction, allowing for sharper angles and finer details, making it a compelling alternative to injection molding.

Traditional plastic injection molding is renowned for its high-volume manufacture but entails significant upfront costs, primarily due to tooling expenses. Injection molds, usually crafted from steel or copper alloy, endure the intense pressures of the injection process, necessitating intricate and heavyweight designs, thereby escalating fabrication costs and lead times.

Choosing between low volume injection molding or thermoforming methods requires careful consideration of various factors to ensure the optimal manufacturing solution for your specific project requirements.

D. Load-bearing is realized by continuous folding surface instead of rib position, which limits surface bearing capacity and bearing capacity of upper frame is small;
